The HOLO-KROME 86440 is a hex socket cap screw designed for secure fastening in applications that require a recessed-drive connection. Sized at 10-24 UNC thread with a 2.25-inch length under head, this screw is partially threaded and accepts a 5/32-inch hex drive. Constructed from alloy steel with a black oxide coating, it delivers solid mechanical strength and moderate corrosion resistance in controlled environments. Manufactured to ASME B18.3 and ASTM A574 standards, it meets established specifications for socket cap fasteners used in industrial, mechanical, and structural assemblies.
This screw is suited for machine assembly, fixture building, tooling plates, and mechanical component mounting where a flush or low-profile fastener head is required. The partially threaded shank is appropriate for applications where thread engagement is needed only at the mating surface, allowing the smooth shank to pass through a clearance hole. Trades and assemblers working in manufacturing, maintenance, and mechanical service commonly install this type of fastener. It is sold in a minimum order quantity of 100 pieces.
Designed as an OEM-style replacement or standard-use socket cap screw for any application requiring a 10-24 UNC hex socket fastener per ASME B18.3 specifications.
Installation requires a 5/32-inch hex key or Allen driver. Ensure the mating tapped hole is clean and free of debris before driving the screw to avoid thread damage. Torque to the value specified by the assembly drawing or equipment manufacturer for 10-24 alloy steel fasteners. Always verify thread engagement depth meets the requirements of the application before final assembly.
