The main purpose of a security fastener is to prevent
unfastening. In most cases special tooling is required both for
installation and removal. This is the main benefit of fasteners
with the security drives.
There are many uses for security fasteners especially
in public facilities. In parks and playgrounds they are used on
signs, benches, fountains, restrooms, swimming pools and play
equipment. In restaurants and hotels use them to fasten down artifacts,
televisions, furniture and lighting fixtures. Amusement parks
use security fasteners on railings, doors, coin-operated equipment
such as money changers, video machines and games. Cases, covers
and cabinets housing computers, fax machines and communication
equipment also use security fasteners to prevent disassembly.
On meters, monitoring equipment, and power supply housing, unauthorized
removal can be avoided by using security fasteners. In general
any fastener which comes in contact with the public and should
not be removed, is a candidate for a security drive fastener.
Security screws are available in pan, round, truss,
oval, flat, button and socket cap head styles. They may have either
machine screw threads or sheet metal threads. The most readily
available materials are zinc plated steel and for more severe
environments - stainless steel. Other materials may be available
by special order. Installation and removal power tool bits and
hand tools are available also. Ask your sales representative for
more information. For a quick comparison of cost vs. degree of
