Value Collection 97116 Hex Head Cap Screw 1/2-13 X 4 in Grade 5

Product Description

The VALUE COLLECTION 97116 is a partially threaded hex head cap screw sized 1/2-13 x 4 inches, manufactured from Grade 5 steel with an uncoated finish. Conforming to ASME B18.2.1, this fastener uses a UNC (Unified National Coarse) thread standard and is measured by length under head. Grade 5 steel provides a reliable balance of tensile strength and ductility for general structural and mechanical assembly applications. The uncoated surface is suitable for indoor or protected environments where corrosion resistance is not a primary concern. This screw is used by maintenance technicians, millwrights, pipefitters, and general contractors in a wide range of industrial and mechanical assembly tasks.

This hex head cap screw is suited for structural fastening in mechanical assemblies, equipment mounting, and general fabrication work. The 1/2-13 UNC thread is one of the most common coarse-thread sizes found in industrial and commercial equipment. Partial threading allows the shank to bear shear loads, making it appropriate for bolted joints where thread engagement in the nut or tapped hole is sufficient and a smooth grip section is beneficial. This screw is sold in a package quantity of 25.

Key Features

• 1/2-13 UNC thread size for broad compatibility with standard nuts and tapped holes
• 4-inch length under head with partial threading for shear-load bearing applications
• Grade 5 steel construction meets minimum tensile strength requirements for medium-duty structural fastening
• Uncoated finish suitable for dry or protected indoor environments
• Conforms to ASME B18.2.1 dimensional standards
• Sold in a pack of 25 fasteners

Compatibility

Designed as a standard 1/2-13 UNC hex head cap screw conforming to ASME B18.2.1, compatible with any 1/2-13 UNC nut, tapped hole, or threaded insert of appropriate grade and clearance in general mechanical and structural assemblies.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or maintenance technician familiar with proper bolted joint procedures. Always use the correct 3/4-inch hex wrench or socket for driving this fastener, and torque to the value specified by the equipment manufacturer or applicable structural code for Grade 5 hardware. Ensure mating threads and contact surfaces are clean and free of debris before assembly. Do not use impact tools at full power without verifying appropriate torque requirements for the joint.
