Value Collection R57001235 Hex Head Cap Screw 3/8-24 X 4 in

Product Description

The VALUE COLLECTION R57001235 is a 3/8-24 UNF hex head cap screw measuring 4 inches under the head, manufactured from 18-8 stainless steel with an uncoated finish. The partially threaded shank provides a bearing surface that resists joint loosening under vibration and load cycling. 18-8 stainless steel delivers solid corrosion resistance suitable for wet, chemical, or outdoor environments where carbon steel would corrode. This fastener is installed by mechanics, millwrights, plumbers, and field technicians across a wide range of structural and mechanical assemblies.

This screw suits applications where corrosion resistance and a fine-thread engagement are both required. The 3/8-24 UNF thread form provides tighter thread pitch than its UNC counterpart, making it well suited to applications requiring precise clamping force or installations in thinner material. Typical use cases include equipment panels, pump housings, bracket assemblies, and mechanical connections in HVAC, plumbing, and industrial service environments. The uncoated finish keeps the fastener electrically and dimensionally true to 18-8 stainless specification.

Key Features

• 3/8-24 UNF fine thread for precise torque control and strong thread engagement
• Partially threaded shank provides a grip area to reduce shear stress at the joint
• 18-8 stainless steel construction resists corrosion in wet and chemical-exposure environments
• Uncoated finish maintains true dimensional tolerance and conductivity
• 4-inch length under head accommodates deeper stack-ups and structural assemblies
• Hex head drive works with standard wrenches and sockets for fast installation

Compatibility

Designed as a standard 3/8-24 UNF hex head cap screw for use in any assembly requiring an inch-series fine-thread fastener in 18-8 stainless steel.

Installation Notes

Install with a properly sized hex wrench or socket to avoid rounding the head. De-grease mating threads before installation and apply an appropriate anti-seize compound when joining stainless-to-stainless to prevent galling. Torque to the value specified by the equipment manufacturer or applicable engineering standard for 3/8-24 stainless fasteners. Power down or depressurize any system before replacing fasteners in live mechanical or fluid assemblies.
