Value Collection 011285PR Hex Socket Cap Screw 3/8-24 Unf

Product Description

The VALUE COLLECTION 011285PR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling fixtures, and industrial equipment. It features a 3/8-24 UNF thread — a fine-pitch unified thread that provides strong clamping force and resistance to loosening under vibration. The screw is fully threaded with 5/8 inch of usable length under the head. Constructed from alloy steel with a black oxide finish, it offers improved corrosion resistance compared to uncoated steel and reduces light reflection in precision or optical assemblies. A 5/16 inch hex socket drive allows installation with a standard Allen key or hex bit driver. Meets ASME/ANSI B18.3 and ASTM A574 standards.

This fastener is suited for applications where a recessed drive head is required to maintain a low or flush profile. Common uses include machine guarding, jig and fixture assembly, hydraulic component mounting, and general industrial maintenance. The fine 3/8-24 UNF thread pitch makes it appropriate for applications requiring precise torque control or where vibration resistance is critical. Maintenance technicians, machinists, and field service personnel working on industrial and mechanical equipment regularly specify this style of cap screw. Sold individually with a minimum order quantity of 100 pieces.

Key Features

• 3/8-24 UNF fine-thread provides strong clamping force and vibration resistance
• Fully threaded body along the 5/8 inch length under head
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish improves mild corrosion resistance and reduces glare
• 5/16 inch hex socket drive compatible with standard Allen keys and hex bit sets
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for use in any application requiring a 3/8-24 UNF fully threaded fastener with a 5/16 inch hex drive.

Installation Notes

Installation is performed with a 5/16 inch hex key or hex socket bit. Power down or de-energize any equipment before disassembling or reassembling fastened components. Follow applicable torque specifications from the equipment manufacturer or relevant ASME standards — no torque values are specified by the fastener supplier. Inspect threads on mating components for damage before installation to avoid galling or cross-threading the alloy steel screw.
