Value Collection 403036PR Hex Head Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 403036PR is a 1/4-20 UNC hex head cap screw with a 3-1/4-inch length under head, manufactured from Grade 2 steel with a zinc-plated finish. The shank is partially threaded, making it well suited for clamping applications where a smooth shank through the near-side material is required. A 7/16-inch hex key or wrench drives the fastener. Licensed tradespeople, maintenance technicians, and mechanical contractors rely on this fastener type for equipment mounting, structural framing connections, and general mechanical assembly across HVAC, plumbing, and electrical installations.

This cap screw fits standard 1/4-20 UNC tapped holes and clearance-drilled assemblies common in light-to-medium-duty trade work. Typical applications include equipment base mounting, bracket fabrication, panel attachment, and utility connections in both residential and commercial settings. The zinc plating provides moderate corrosion resistance for indoor and semi-sheltered outdoor environments. Sold individually with a minimum order quantity of 100 pieces per order.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes and nuts
• 3-1/4-inch length under head accommodates thicker stack-ups and long-reach clamping
• Partially threaded shank provides a smooth bearing surface through clearance holes
• Grade 2 steel construction meets general-purpose mechanical fastening requirements
• Zinc-plated finish offers corrosion resistance in dry and semi-exposed conditions
• 7/16-inch hex drive compatible with standard wrenches and sockets

Compatibility

Designed for use in any application requiring a 1/4-20 UNC hex head cap screw with a 3-1/4-inch length under head, including equipment mounting and structural assembly in HVAC, plumbing, and electrical trade work.

Installation Notes

Install using a 7/16-inch open-end, box, or socket wrench. Ensure the mating hole is tapped to 1/4-20 UNC or that an appropriate nut is used for through-bolt applications. De-energize and lock out equipment before fastening or removing hardware on live mechanical or electrical assemblies, following applicable OSHA lockout/tagout procedures. Do not exceed the load limits appropriate for Grade 2 steel fasteners in structural or high-vibration applications.
