Value Collection 403042PR Hex Head Cap Screw 1/4-20 X 4 in

Product Description

The VALUE COLLECTION 403042PR is a 1/4-20 x 4 inch hex head cap screw manufactured from Grade 2 steel with a zinc-plated finish. It features partial threading along the shank and is dimensioned under the Unified National Coarse (UNC) thread standard. The zinc plating provides a basic level of corrosion resistance suitable for general-purpose fastening applications. At 0.06 pounds per piece, this screw is sized for light to medium structural and mechanical assemblies. Installation requires a 7/16 inch hex wrench or socket driver. It is commonly installed by maintenance technicians, HVAC service professionals, electricians, and plumbers when securing panels, brackets, and equipment enclosures.

This cap screw is intended for general industrial and trade applications where a standard inch-series, partially threaded fastener is required. The 4 inch length under head makes it well suited for through-bolt applications in thicker substrates or stacked assemblies. It is sold individually with a minimum order quantity of 100 pieces, making it appropriate for bulk restocking of service vehicles, shop bins, and maintenance kits across HVAC, plumbing, electrical, and pool equipment service operations.

Key Features

• 1/4-20 UNC thread form for compatibility with standard inch-series nuts and tapped holes
• Partial threading allows the smooth shank to bear shear loads in through-bolt applications
• Zinc-plated finish provides basic corrosion resistance for indoor and sheltered outdoor use
• Grade 2 steel construction suitable for general-purpose, non-critical fastening
• 7/16 inch hex drive size works with standard wrenches and sockets carried by most trades
• Sold per piece with a minimum order quantity of 100 for bulk bin and fleet stocking

Compatibility

Designed as a general-purpose inch-series hex head cap screw for use with any standard 1/4-20 UNC tapped hole or nut in light to medium mechanical and structural assemblies.

Installation Notes

Installation requires a 7/16 inch open-end wrench, box wrench, or socket. For bolted joint integrity, the mating nut or tapped hole should also conform to the UNC thread standard. Do not exceed the torque rating appropriate for Grade 2 fasteners in the application material. Ensure the fastener is fully seated and the smooth shank section spans the shear plane before final torque is applied.
