Value Collection 403196PR Hex Head Cap Screw 1/2-13x3 in

Product Description

The VALUE COLLECTION 403196PR is a 1/2-13 x 3 inch hex head cap screw designed for general-purpose fastening in mechanical, structural, and industrial assembly applications. It is manufactured from Grade 2 steel with a zinc plating finish that provides basic corrosion resistance in dry and mildly exposed environments. The fastener features Unified National Coarse (UNC) threading and is partially threaded along its 3-inch length under the head, which is standard practice for longer-bodied screws in clamped-joint assemblies. A 3/4-inch hex key size allows installation and removal with standard wrench tooling.

This cap screw is suited for use in light structural connections, equipment mounting, HVAC frame assemblies, panel brackets, and general mechanical fabrication where Grade 2 steel meets the load requirements. Partially threaded shanks are preferred in through-bolt and clamped-joint configurations where the unthreaded shank provides a bearing surface against the connected materials. This fastener ships individually but carries a minimum order quantity of 50 pieces.

Key Features

• 1/2-13 UNC thread size for compatibility with standard inch-series nuts and tapped holes
• 3-inch length under head with partial threading — unthreaded shank provides a bearing surface for clamped joints
• Grade 2 steel construction suitable for general-purpose, non-critical fastening applications
• Zinc-plated finish offers basic corrosion protection in dry or mildly humid environments
• 3/4-inch hex drive compatible with standard open-end, box, and socket wrenches

Compatibility

Designed as a standard inch-series hex head cap screw compatible with any 1/2-13 UNC tapped hole or hex nut conforming to ASME B18.2.1 dimensional standards.

Installation Notes

Installation is performed with a 3/4-inch open-end, box-end, or socket wrench. Verify that the mating nut or tapped hole is 1/2-13 UNC thread form before assembly. Grade 2 fasteners are not rated for high-strength structural connections — confirm that the application load requirements do not exceed the material grade rating. Inspect threads and plating for damage before installation; do not use fasteners with deformed threads.
