Value Collection 011243PR Hex Socket Cap Screw 5/16-24 Unf

Product Description

The VALUE COLLECTION 011243PR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies. Manufactured from alloy steel with a black oxide finish, it offers corrosion resistance and a clean appearance suited to precision equipment. The screw features a 5/16-24 UNF thread size and measures 2.25 inches under the head, with partial threading along the shank. Drive engagement is through a 1/4-inch hex socket. It meets ASME/ANSI B18.3 and ASTM A574 standards, making it a recognized choice for demanding structural and mechanical fastening tasks. Installation requires a 1/4-inch hex key or Allen driver.

This screw is suited for use in industrial machinery, mechanical assemblies, and precision equipment where fine-thread fastening and reliable clamping force are required. The 5/16-24 UNF fine thread pattern provides greater tensile strength and finer adjustment than coarse-thread alternatives. The black oxide coating is appropriate for indoor or lightly protected environments. Typical installers include machinists, millwrights, mechanical technicians, and general maintenance professionals working with steel or aluminum assemblies.

Key Features

• 5/16-24 UNF fine thread for high clamping force and precise adjustment
• Alloy steel construction meets ASTM A574 high-strength fastener requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Partially threaded shank allows controlled engagement depth
• 1/4-inch hex drive compatible with standard Allen keys and hex socket drivers
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any assembly requiring a 5/16-24 UNF partially threaded fastener with a 1/4-inch hex drive.

Installation Notes

Installation requires a 1/4-inch hex key or socket driver torqued to the appropriate value for the joint material and application. De-energize or shut down any equipment before fastener service. Verify thread engagement depth against the partial-thread shank length before final torque. Follow applicable mechanical codes and manufacturer assembly specifications for the host equipment.
