Value Collection 403038PR Hex Head Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 403038PR is a 1/4-20 UNC hex head cap screw manufactured from Grade 2 steel with a zinc-plated finish for corrosion resistance. At 3-1/2 inches in length under the head and partially threaded, this fastener is suited for general-purpose mechanical assembly where a full thread run is not required. The zinc plating provides a baseline level of protection in mildly corrosive environments. Driven with a 7/16-inch hex key or wrench, this screw meets standard inch-system UNC thread specifications. Sold individually, with a minimum order quantity of 100 pieces.

This hex head cap screw is used in a wide range of light-duty industrial, mechanical, and trade applications including equipment assembly, structural bracketing, HVAC equipment mounting, electrical enclosures, and general maintenance work. The partially threaded shank allows for clamping force between joined materials without thread engagement through the full grip length. Suitable for use in residential and light commercial settings where Grade 2 steel tensile strength is appropriate for the load requirements.

Key Features

• 1/4-20 UNC thread form for compatibility with standard inch-system tapped holes and nuts
• 3-1/2 inch length under head with partial threading for controlled clamping grip
• Grade 2 steel construction for general-purpose fastening applications
• Zinc-plated finish provides corrosion resistance in light-duty environments
• 7/16-inch hex drive fits standard wrenches and sockets
• Sold per piece with a minimum order quantity of 100 units

Compatibility

Designed for use with standard 1/4-20 UNC tapped holes and matching hex nuts in general-purpose inch-system mechanical assemblies.

Installation Notes

Installation requires a 7/16-inch wrench or socket. Ensure mating threads and tapped holes are clean and free of debris before driving. Do not exceed the tensile rating of Grade 2 steel by applying torque beyond hand-tight plus the turn specified for the application per relevant ASME or industry standards. Power down or de-energize any equipment before fastener replacement on live assemblies.
