Value Collection R57001197 Hex Head Cap Screw 1/4-20

Product Description

The VALUE COLLECTION R57001197 is a 1/4-20 UNC hex head cap screw measuring 5-1/2 inches in length under the head. Manufactured from 18-8 stainless steel, this fastener offers solid corrosion resistance for applications exposed to moisture or mild chemicals. The shank is partially threaded, which provides a grip zone for clamping and is well suited to assemblies where full thread engagement is not required or desired. At 0.3 pounds per unit, this is a standard-weight fastener appropriate for mechanical, HVAC bracket, plumbing support, and general trade assembly work. No coating is applied, leaving the stainless finish exposed and ready for direct installation.

This cap screw is commonly used in residential and light commercial trade applications where a corrosion-resistant inch-series fastener is required. Typical scenarios include equipment mounting, structural bracket attachment, and component assembly on HVAC systems, plumbing fixtures, and electrical enclosures. The 1/4-20 UNC thread is one of the most widely used inch-series fastener sizes, making this screw easy to source matching hardware for in the field.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet or outdoor environments
• Partially threaded shank allows for a clamping grip zone between fastened components
• 1/4-20 UNC thread standard ensures broad hardware compatibility
• 5-1/2 inch length under head suits deeper stack assemblies or through-bolt applications
• Uncoated finish — no risk of coating interference with mating threads or contact surfaces

Compatibility

Designed as a standard inch-series hex head cap screw compatible with any 1/4-20 UNC tapped hole or matching nut, suitable for general mechanical and trade assembly applications.

Installation Notes

Installation is appropriate for any trade technician performing mechanical assembly or equipment mounting. Use a standard hex wrench or socket driver sized for a 1/4-inch hex fastener. Ensure mating threads are clean and free of debris before installation. Do not overtighten stainless fasteners, as 18-8 stainless is susceptible to galling — apply an anti-seize compound when torque requirements are critical.
