Value Collection 581838BR Hex Socket Cap Screw 1-14 Unf

Product Description

The VALUE COLLECTION 581838BR is a hex socket cap screw designed for high-strength fastening applications in industrial and mechanical assemblies. It features a 1-14 UNF thread form, a 3-inch length under head, and full threading along its entire shank. The 3/4-inch hex drive socket accommodates a standard hex key or Allen wrench for reliable torque transmission. Manufactured from alloy steel with a black oxide coating, this screw delivers corrosion resistance and a consistent surface finish suited to demanding service conditions. It meets ASME/ANSI B18.3 and ASTM A574 dimensional and mechanical standards, making it a recognized choice for precision fastener replacement and new assembly work.

This screw is suited for use in machinery, tooling fixtures, hydraulic components, and structural assemblies where a recessed-drive, high-tensile fastener is required. The 1-14 UNF fine thread pitch provides superior thread engagement and resistance to vibration loosening, making it appropriate for dynamic load applications in manufacturing, maintenance, and repair environments. Machinists, millwrights, and maintenance technicians are the primary installers.

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for use in any assembly requiring a 1-14 UNF fully threaded socket head cap screw.

Installation Notes

Installation should be performed by a qualified mechanic or millwright using a properly sized 3/4-inch hex key or drive tool. Always de-energize and lock out equipment before servicing fastened assemblies. Apply thread lubricant or thread-locking compound as required by the assembly specification. Do not exceed the torque value specified by the equipment manufacturer for this thread size and grade.
