Product Description
With a low-profile, countersunk head, flat socket head cap screws are ideal for applications requiring
a strong fastener with a flush mount. For example, flat socket cap screws are often used in projects
what require moving parts to pass over a fastened area. Because of their ability to mount flush with
the surface, they are less apt to snag objects moving overhead. Flat head socket screws are crafted
from either alloy or stainless steel with plain, zinc or black oxide finish and they are made to conform
to ASME B18.3, DIN 7991 or ISO 10642 specifications. Use an allen wrench (hex key) for installation
and removal.
