Value Collection R57001142 Hex Head Cap Screw 3/8-16

Product Description

The VALUE COLLECTION R57001142 is a fully threaded hex head cap screw in 3/8-16 UNC thread size with a 4-3/4 inch length under head. Manufactured from 18-8 stainless steel and left uncoated, this fastener delivers reliable corrosion resistance in wet, outdoor, and chemical-exposure environments. The UNC thread form provides strong thread engagement in standard inch-system tapped holes and nuts. Fully threaded along the entire shank length, it is well suited for clamping applications where maximum thread engagement or through-bolting is required. Licensed tradespeople and maintenance technicians across HVAC, plumbing, electrical, and mechanical service trades use fasteners like this for equipment mounting, panel attachment, and structural assembly work.

This cap screw is appropriate for general industrial and commercial maintenance applications where stainless steel fasteners are specified. Typical use cases include equipment support structures, corrosion-prone mechanical assemblies, outdoor or wet-location mounting, and food-service or chemical-processing environments where carbon steel fasteners are not acceptable. The 3/8-16 UNC thread is one of the most common inch-series fastener sizes, making this screw broadly compatible with standard hex nuts, locknuts, and threaded inserts of the same thread specification.

Key Features

• 18-8 stainless steel construction provides strong corrosion and oxidation resistance
• Fully threaded shank maximizes thread engagement for through-bolt and clamping applications
• 3/8-16 UNC thread standard ensures compatibility with common inch-series hardware
• Uncoated finish maintains dimensional accuracy and avoids coating incompatibility in sensitive assemblies
• 4-3/4 inch length under head suits deeper clamping stacks and thicker structural members

Compatibility

Designed for use with standard 3/8-16 UNC hex nuts, locknuts, flat washers, and threaded inserts in inch-series fastener applications.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson following applicable mechanical and structural codes. Ensure mating threads are clean and free of debris before installation. When torquing 18-8 stainless steel fasteners, use appropriate anti-seize compound on threads to prevent galling, which is common with stainless-to-stainless contact. Do not impact-drive stainless steel cap screws, as this increases the risk of galling and thread damage.
