Value Collection R63033960 Hex Head Cap Screw 1/4-28

Product Description

The VALUE COLLECTION R63033960 is a hex head cap screw designed for general fastening applications where corrosion resistance and dimensional precision are required. Manufactured from 18-8 stainless steel, this fastener features a 1/4-28 UNF (Unified Fine) thread pattern and measures 1-1/2 inches under the head. The 7/16-inch hex drive is compatible with standard wrenches and sockets. This screw is appropriate for use in plumbing, HVAC panel assemblies, electrical enclosures, and light mechanical assemblies where a stainless fastener is specified. Installation is performed by qualified tradespeople or maintenance personnel using standard hand or power tools.

This fastener suits residential and light commercial applications where fine-thread engagement and stainless steel corrosion resistance are priorities. Fine-thread UNF fasteners are typically chosen over coarse-thread when greater thread engagement per inch is needed in thinner material or tapped metal components. The 18-8 grade stainless steel provides good resistance to rust and oxidation in moderately corrosive environments, making it a common choice for HVAC brackets, plumbing access panels, and electrical enclosure hardware.

Key Features

• 18-8 stainless steel construction for corrosion resistance in wet or humid environments
• 1/4-28 UNF fine-thread pattern for increased thread engagement in metal components
• 1-1/2 inches length under head for adequate grip depth in typical panel and bracket assemblies
• 7/16-inch hex head drive compatible with standard wrenches and sockets
• Inch measurement system with Length Under Head measurement type

Compatibility

Designed as a standard 1/4-28 UNF hex head cap screw suitable for use in equipment assemblies, enclosures, and structural brackets that specify an 18-8 stainless steel fastener in this thread size and length.

Installation Notes

Installation should be performed using a properly sized 7/16-inch wrench or socket to avoid rounding the hex head. Ensure the mating thread is clean and free of debris before driving the fastener. Do not overtighten stainless steel fasteners, as galling can occur; applying an appropriate anti-seize compound to the threads is standard practice when working with stainless-to-stainless connections. Follow applicable mechanical and structural codes for torque and fastener spacing requirements on the equipment being serviced.
