Value Collection 011245PR Hex Socket Cap Screw 5/16-24 Unf

Product Description

The VALUE COLLECTION 011245PR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and industrial equipment. It features a 5/16-24 UNF thread size with a 2-1/2 inch length under the head and accepts a 1/4 inch hex drive. The screw is partially threaded, which maintains clamping strength through the unthreaded shank. Constructed from alloy steel and finished with a black oxide coating, it provides moderate corrosion resistance and reduces surface reflectivity. Installation requires a standard 1/4 inch hex key or Allen driver. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, confirming material strength and dimensional compliance for critical fastening work.

This screw is suited for precision mechanical assemblies, machine tool fixtures, jigs, and equipment frames where fine-thread engagement and high tensile strength are required. Fine-thread UNF fasteners are commonly used in applications with thin materials, vibration-prone assemblies, or where greater thread engagement per inch is needed compared to UNC. It is installed by machinists, millwrights, and maintenance technicians across manufacturing, fabrication, and industrial maintenance settings. The black oxide finish makes it a practical choice for applications where a low-profile, non-reflective appearance is preferred.

Key Features

• 5/16-24 UNF fine thread for strong engagement and vibration resistance
• 2-1/2 inch length under head with partial threading for full shank clamping
• 1/4 inch hex socket drive for torque application with standard Allen tools
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish provides moderate corrosion resistance and non-reflective surface
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for mechanical assemblies, fixtures, and equipment requiring 5/16-24 UNF fine-thread fasteners with a 2-1/2 inch grip length.

Installation Notes

Installation requires a 1/4 inch hex key or Allen driver; use a torque wrench with appropriate hex bit for controlled torquing in critical assemblies. Ensure mating tapped holes are clean and free of debris before installation. Black oxide fasteners are not intended for outdoor or high-moisture environments without additional corrosion protection. Follow applicable mechanical and structural codes for the specific application.
