Item 1.  Security and Issuer

          Item to Schedule 13D is amended, in pertinent part, as 

follows:

          This Amendment No. 33 to Schedule 13D on Hi-Shear Industries,

Inc. (the "Issuer") is being filed on behalf of the undersigned to  

amend the Schedule 13D, as amended (the "Schedule 13D") which was 

originally filed on May 21, 1987.   This is Reporting Persons' latest

Amendment to Schedule 13D on the Issuer.  Unless otherwise indicated, 

all capitalized terms used herein but not defined shall have the same 

meaning as set forth in the Schedule 13D.


Item 2.   Identity and Background
          This statement is being filed by Mario J. Gabelli ("Mr.
Gabelli") and various entities which he directly or indirectly controls
and for which he acts as chief investment officer.  These entities,
except for Lynch Corporation ("Lynch"), Spinnaker Industries,
Incorporated ("Spinnaker", formerly known as Safety Railway Services
Corporation), Western New Mexico Telephone Company ("Western New
Mexico") and Inter-Community Telephone Company ("Inter-Community")
engage in various aspects of the securities business, primarily as
investment advisor to various institutional and individual clients,
including registered investment companies and pension plans, as
broker/dealer and as managing general partner of various private
investment partnerships.  Certain of these entities may also make
investments for their own account. 
          The foregoing persons in the aggregate often own beneficially
more than 5% of a class of equity securities of a particular Issuer. 
Although several of the foregoing persons are treated as institutional
investors for purposes of reporting their beneficial ownership on the
short-form Schedule 13G, the holdings of those who do not qualify as
institutional investors may exceed the 1% threshold presented for
filing on Schedule 13D or implementation of their investment philosophy
may from time to time require action which could be viewed as not
completely passive.  In order to avoid any question as to whether their
beneficial ownership is being reported on the proper form and in order
to provide greater investment flexibility and administrative
uniformity, these persons have decided to file their beneficial
ownership reports on the more detailed Schedule 13D form rather than on
the short-form Schedule 13G and thereby to provide more expansive
disclosure than may be necessary. 
          (a), (b) and (c) - This statement is being filed by one or
more of the following persons: Gabelli Funds, Inc. ("GFI"), GAMCO
Investors, Inc. ("GAMCO"), Gabelli Securities, Inc. ("GSI"), Gabelli &
Company, Inc. ("Gabelli & Company"), Gabelli Performance Partnership
("GPP"), GLI, Inc. ("GLI"), The Gabelli Associates Fund ("Gabelli As-
sociates"), Gabelli Associates Limited ("GAL"), The Gabelli & Company,
Inc. Profit Sharing Plan (the "Plan"); Gabelli International Limited
("GIL"), Gabelli International II Limited ("GIL II"), ALCE Partners,
L.P. ("ALCE"), Gabelli Multimedia Partners, L.P. ("Multimedia
Partners"), Mario J. Gabelli ("Mr. Gabelli"), Lynch, Spinnaker, Western
New Mexico and Inter-Community. Those of the foregoing persons signing
this Schedule 13D are hereafter referred to as the "Reporting Persons".
          GAMCO, a majority owned subsidiary of GFI, is an investment
adviser registered under the Investment Advisers Act of 1940, as
amended.  GAMCO is a money manager providing discretionary managed
account services in the equity area for employee benefit plans, private
investors, endowments and foundations. 
          Gabelli & Company, a wholly-owned subsidiary of GSI, is a
broker-dealer registered under the l934 Act, which as a part of its
business regularly purchases and sells securities for its own account. 
In addition, shares are held for clients who have granted Gabelli &

          For information required by instruction C to Schedule 13D

reference is made to Schedule I annexed hereto and incorporated herein
by reference. 
          (d) and (e) On December 8, 1994, the SEC instituted and
simultaneously accepted offers for the settlement of an administrative
proceeding againts Gabelli & Company, Inc.  The order instituting the
proceeding included a finding, which Gabelli & Company and GAMCO
neither admitted nor denied, that they failed to impliment and maintain
policies and procedures reasonably designed to prevent the misuse of
material, nonpublic information by not sepecifically addressing the
special circumstances that arose from their affiliation with Lynch
Corporation, a public company.  To resolve this matter, Gabelli &
Company and GAMCO agreed to cease and desist from violating Section
15(f) of the Securities Exchange Act of 1934 (the "Exchange Act") and
Section 204A of the Investment Advisers Act of 1940 (the "1940 Act"),
respectively.  They further agreed to each pay a civil penalty in the
amount of $50,000, and to retain, and adopt the recommendations of, an
independant consultant regarding their Section 15(f) and Section 204A
policies and procedures.  
          On December 13, 1991, the Virginia State Corporation
Commission entered an order of settlement in final disposition of
matters arising from an allegation that GAMCO had transacted business
in Virginia as an investment adviser without having been registered as
such under Virginia Code Section 13.1-504A or an exemption therefrom. 
GAMCO consented to the entry of the order without admitting or denying
the allegation and without a hearing.  The terms of the order provide
that GAMCO would pay a fine and cots totalling fifty-five thousand
dollars and would not transact business in Virginia as an investment
adviser unless it was registered as such under section 13.1-504A or was
exempt from registration.  
     (f) - Reference is made to Schedule I hereto. 


Item 3.   Source and Amount of Funds or Other Consideration
          Item to Schedule 13D is amended, in pertinent part, as
follows:

$378,675 and $35,000, respectively, of funds that were provided through
the accounts of certain of their investment advisory clients (and, in
the case of some of such accounts at GAMCO, may be through borrowings
from client margin accounts) in order to purchase the Securities for
such clients.  GIL used approximately $49,500 to purchase the
Securities reported by it.

Item 5.   Interest In Securities Of The Issuer
          Items 5 (a) and (b) to Schedule 13 D are amended, in
pertinent part, as follows:
          (a)  The aggregate number and percentage of Securities to
which this Schedule 13D relates is 2,193,990 shares, representing
37.47% of the 5,854,618 shares outstanding in the Issuer's most
recently filed Form 10-Q dated February 28, 1995.  The Reporting
persons beneficially own those Securities as follows:
                         Shares of           % of
                         Common              Class of
Name                     Stock               Common  

Gabelli Funds:
  As Principal                  0                0.00%
  As Agent                253,500                4.32%        

GAMCO
  As Principal                  0                0.00%
  As Agent              1,923,740               32.86%

Mario J. Gabelli            9,750                0.17%

GIL                         7,000                0.12%

          Mr. Gabelli is deemed to have beneficial ownership of the
Securities beneficially owned by each of the foregoing persons and GFI is
deemed to have beneficial ownership of the securities owned beneficially
by each of the foregoing persons other than Mr. Gabelli. 
          (b) Each of the Reporting Persons and Covered Persons has the
sole power to vote or direct the vote and sole power to dispose or to
direct the disposition of the Securities reported for it, either for its
own benefit or for the benefit of its investment clients or its partners,
as the case may be, except that: (i) GAMCO Investors, Inc. does not have
authority to vote 254,400 of the reported shares; (ii) since the aggregate
voting interest of all joint filers exceeds 25% of the total voting
interest in the Issuer, with respect to the 70,000 shares (1.20%) of
Common Stock held by The Gabelli Asset Fund, the 6,000 shares (0.10%) of
Common Stock held by The Gabelli ABC Fund, the 145,000 shares (2.48%) held
by the Gabelli Equity Trust Inc., the 6,000 shares (0.10%) held by the
Gabelli Capital Asset Fund, and the 26,500 shares (0.45%) held by The
Gabelli Small Cap Growth Fund, the proxy voting committee of each such
Fund has taken and exercises in its sole discretion the entire voting
power with respect to the shares held by each such Fund, until its proxy
committee determines otherwise and, accordingly, GFI has no voting
authority with regard to the shares held by such Funds; and, (iii) the
power of Mr. Gabelli and GFI is indirect with respect to Securities
beneficially owned directly by other Reporting Persons.
