The dome shaped head is wider and has a lower profile than a socket cap screw.
Knurled cylindrical sides and hexagonal recess.
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 and grade 8 hex cap screws while requiring less surface area or counterbore since the fastener is internally wrenched.
Made from stainless steel. The dome shaped head is wider and has a lower profile than a socket cap screw. Knurled cylindrical sides and hexagonal recess.
