Value Collection 97408 Hex Head Cap Screw 1/2-20 X 2 in Grade 5

Product Description

The VALUE COLLECTION 97408 is a 1/2-20 hex head cap screw designed for general-purpose fastening in mechanical, structural, and industrial assembly applications. Measuring 2 inches under the head with a Unified Fine Thread (UNF) profile, this partially threaded fastener is manufactured from Grade 5 steel in an uncoated finish. Grade 5 steel provides a reliable strength level for most commercial and light industrial joint applications. Conforming to ASME B18.2.1, the dimensional standard for hex head cap screws, this fastener delivers consistent head geometry and thread accuracy across the 100-piece package. Licensed contractors, millwrights, and maintenance technicians are the primary installers.

This hex head cap screw is suited for use in assemblies requiring a fine-thread fastener where vibration resistance and precise clamping load are priorities. The 1/2-20 UNF thread engages more threads per inch than its coarse-thread equivalent, making it a common choice in metal-to-metal joints, machinery frames, brackets, and equipment mounting applications across industrial, HVAC structural, and mechanical service environments. The partial threading allows the unthreaded shank to act as a bearing surface in clearance-fit holes.

Key Features

• 1/2-20 UNF thread for higher thread engagement versus coarse-thread equivalents
• Grade 5 steel construction meets standard strength requirements for commercial fastening
• Partially threaded shank provides a bearing surface in clearance-fit applications
• Uncoated finish — suitable for dry indoor environments or applications where coating is applied post-assembly
• Conforms to ASME B18.2.1 for consistent head dimensions and tolerances
• Sold in a 100-piece package with a minimum order quantity of 1

Compatibility

Designed as a standard 1/2-20 UNF hex head cap screw per ASME B18.2.1, suitable for use in any application calling out this thread size, length, and Grade 5 steel specification.

Installation Notes

Installation is performed by qualified mechanics, millwrights, or maintenance technicians using a standard hex wrench, socket, or open-end wrench sized for a 1/2-inch hex head fastener. Confirm mating thread size and pitch before installation to avoid cross-threading. Do not exceed the rated clamp load for Grade 5 hardware. Follow applicable industry standards and equipment manufacturer torque guidelines when determining final tightening values.
