Value Collection 402060PR Hex Head Cap Screw 5/16-18

Product Description

The VALUE COLLECTION 402060PR is a 5/16-18 UNC hex head cap screw with a 1-1/2 inch length under head, manufactured from Grade 2 steel with a bright uncoated finish. The fastener is partially threaded, which provides a smooth shank section useful in applications requiring controlled clamping force or precise bolt alignment. This is a standard inch-series fastener suitable for general mechanical assembly work across HVAC, plumbing, electrical, and light structural applications. Installation is handled by any trade or maintenance professional using standard hex tooling.

This screw is used in general-purpose fastening applications where Grade 2 steel strength is sufficient and corrosion resistance is not the primary requirement. The uncoated bright finish makes it appropriate for dry or protected indoor environments. The partial threading allows the unthreaded shank to pass cleanly through clearance holes before engaging the mating thread, which is a common design requirement in mechanical assemblies and equipment panels. Minimum order quantity is 100 pieces, sold in single-unit packaging quantities.

Key Features

• 5/16-18 UNC thread with 1-1/2 inch length under head for common assembly depths
• Partially threaded shank allows accurate alignment through clearance holes
• Grade 2 steel construction meets standard tensile requirements for general fastening
• Bright uncoated finish for use in dry, protected interior environments
• Inch measurement system with UNC thread standard for wide tooling compatibility

Compatibility

Designed as a general-purpose inch-series UNC hex head cap screw compatible with any 5/16-18 tapped hole or standard nut in mechanical assemblies, equipment frames, and structural brackets requiring Grade 2 steel fasteners.

Installation Notes

Installation requires a standard 1/2 inch hex wrench or socket driver. Always power down or de-energize any equipment before accessing fastener points in electrical or HVAC assemblies. Do not exceed the torque rating appropriate for Grade 2 steel at this thread size, and do not use this uncoated fastener in wet or corrosive environments where a coated or stainless alternative would be required.
