Value Collection -40235-4 Hex Socket Cap Screw 5/16-24 Unf

Product Description

The VALUE COLLECTION -40235-4 is a partially threaded hex socket cap screw designed for secure mechanical fastening in high-load applications. It features a 5/16-24 UNF thread size and measures 3-1/2 inches in length under the head. The 1/4-inch hex drive socket accepts a standard Allen or hex key for installation. Manufactured from alloy steel with a black oxide finish, this cap screw offers solid tensile strength and basic corrosion resistance. It meets ASME/ANSI B18.3 and ASTM A574 fastener standards. Machinists, millwrights, maintenance technicians, and mechanical contractors typically install this type of fastener in equipment assemblies, fixtures, and structural mechanical joints.

This screw is suited for industrial, commercial, and light manufacturing applications where a recessed-drive cap screw is required. The partial threading allows for a strong clamping grip between joined materials, making it appropriate for bolted assemblies where the unthreaded shank spans a clearance hole. The black oxide coating provides a low-glare, low-profile finish commonly specified in tooling, machinery frames, and equipment enclosures. Sold individually, with a minimum order quantity of 10 units.

Key Features

• 5/16-24 UNF thread for fine-thread engagement and precise torque control
• 3-1/2 inch length under head suits deeper fastening applications
• Partially threaded shank provides clamping force across clearance holes
• 1/4-inch hex drive accepts standard Allen keys and hex bit drivers
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish reduces light reflection and provides mild corrosion resistance

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for mechanical assemblies, fixtures, and equipment requiring a 5/16-24 UNF fine-thread fastener with a 1/4-inch internal hex drive.

Installation Notes

Installation is performed using a 1/4-inch hex key or Allen-drive bit. Power down and de-energize any equipment before accessing fastened assemblies. Verify thread engagement and torque to the specification required by the host assembly design — do not rely on a generic torque value for alloy socket cap screws without consulting the application engineer or OEM documentation. Follow applicable mechanical codes and workplace fastener standards for the installation environment.
