6-32 X 1/2 SHCS ALLOY PATCH
Description
An externally threaded fastener with unified threads, a cylindrical head with a flat chamfered top surface, knurled cylindrical sides, and hexagonal recess, made from alloy steel.
Application/Advantages
Ideal for precision assembly work with close tolerances and applications needing a well-tooled appearance. Supplies greater tensile strength than equivalent sizes of Grade-5 or Grade-8 hex head cap screws while requiring less surface area or counterbore since the fastener is internally wrenched.
Heat Treatment
Cap screws shall be heat treated by oil quenching from above the transformation temperature and then tempered by reheating to at least 700°F to achieve mechanical properties as defined in ASTM A574.
Hardness
Nylon patch is a pre-applied inert thread locking process that creates instant retention and sealing properties along with the added benefit of adjustability and reusability. The engineered plastic material is chemical resistant and eliminates the need for costly lock washers, cotter pins, or castellated nuts.
When assembled with a mating part, the nylon patch is compressed. Due to the elastic memory, it resists this compression and acts as a wedge, increasing the metal to metal contact 180° opposite the material. This mechanical force creates a strong, yet fully adjustable lock which will not weaken, even under extreme vibration.
