Value Collection 581965BR Hex Socket Cap Screw 1-1/2-12 Unf

Product Description

The VALUE COLLECTION 581965BR is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. This fastener features a 1-1/2-12 UNF thread size with a 4-inch length under head and is fully threaded for maximum thread engagement. Manufactured from alloy steel with a black oxide finish, it offers improved corrosion resistance and reduced light reflection in service environments. The 1-inch hex drive socket head accommodates standard hex keys and drive tools, making installation straightforward in confined or close-tolerance applications. It meets ASME/ANSI B18.3 and ASTM A574 standards for socket head cap screws.

This cap screw is suited for use in machinery, tooling fixtures, hydraulic assemblies, and other industrial equipment where fine-thread engagement and high clamping force are required. The 1-1/2-12 UNF thread pitch is commonly specified in applications demanding precise torque control and resistance to vibration loosening. Maintenance technicians, millwrights, and mechanical assemblers typically install this fastener in production and field service settings.

Compatibility

Designed as an OEM-style replacement or direct-use fastener for industrial machinery, fixtures, and assemblies specifying 1-1/2-12 UNF hex socket cap screws per ASME/ANSI B18.3 and ASTM A574.

Installation Notes

Installation is typically performed by millwrights, mechanical assemblers, or maintenance technicians using a calibrated torque wrench and a 1-inch hex key or socket drive. Ensure mating threads are clean and free of debris before installation. De-energize and lock out equipment per OSHA lockout/tagout procedures before servicing fastened assemblies. Do not substitute a coarse-thread fastener in an application specified for UNF thread form.
