Value Collection 307238BR Hex Socket Cap Screw 1-8 Unc

Product Description

The VALUE COLLECTION 307238BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and structural connections. It features a 1-8 UNC thread size with a 3-1/4 inch length under the head and is fully threaded along its entire shaft. The 5/8 inch hex drive socket accepts a standard hex key or Allen wrench. Manufactured from alloy steel with a black oxide finish coating, this fastener meets ASTM A574 specifications, the recognized standard for alloy steel socket-head cap screws. It is suited for use in machine shops, maintenance environments, and production assembly work where a recessed-drive, high-strength screw is required.

This socket cap screw is appropriate for industrial and commercial fastening tasks where a low-profile head and internal hex drive are needed. Common applications include machine frames, jigs and fixtures, hydraulic components, and general metalworking assemblies. The fully threaded configuration provides consistent clamping force across the full engaged length, making it well-suited for through-hole and thinner material applications. Licensed trades and industrial mechanics routinely use this style of fastener wherever torque requirements exceed the capacity of standard machine screws.

Key Features

• 1-8 UNC thread form for broad compatibility with standard inch-series tapped holes
• Fully threaded shaft maximizes thread engagement across the entire 3-1/4 inch length under head
• 5/8 inch hex socket drive accepts common Allen or hex key tooling
• Alloy steel construction meets ASTM A574 for high-strength socket cap screw requirements
• Black oxide finish coating provides mild corrosion resistance and reduces surface reflectivity

Compatibility

Designed as a direct-fit replacement or new installation fastener for any application requiring a 1-8 UNC, fully threaded alloy steel hex socket cap screw conforming to ASTM A574.

Installation Notes

Installation requires a 5/8 inch hex key or Allen wrench of appropriate length to achieve proper seating torque. Always verify that the mating tapped hole is clean, undamaged, and cut to 1-8 UNC specification before installation. Apply thread lubricant or thread-locking compound only as specified by the assembly's engineering requirements. Follow applicable industry torque guidelines for ASTM A574 alloy steel socket cap screws when torquing to final specification.
