Value Collection R57001055 Hex Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION R57001055 is a hex socket cap screw designed for secure fastening in applications where a recessed-drive, high-profile head is required. Sized at 3/8-16 UNC thread with a 3-3/4 inch length under head, it accepts a 5/16 inch hex key drive. Constructed from 18-8 stainless steel with a bright uncoated finish, it resists corrosion in wet and mildly corrosive environments. This fastener is installed by mechanics, maintenance technicians, pipefitters, and HVAC or plumbing service professionals working with stainless hardware assemblies.

This cap screw is suited for general industrial, mechanical, and trade-service applications where a coarse 3/8-16 UNC thread is specified. Typical uses include mounting brackets, equipment frames, pump housings, and structural assemblies in both commercial and light industrial settings. The 18-8 stainless steel construction makes it a practical choice in environments with moisture exposure, such as mechanical rooms, rooftop equipment, and pool-mechanical installations.

Key Features

• 3/8-16 UNC coarse thread for broad compatibility with standard tapped holes
• 3-3/4 inch length under head for use in deeper or stacked assemblies
• 5/16 inch hex socket drive for precise torque application with standard hex keys or Allen drivers
• 18-8 stainless steel construction provides corrosion resistance in wet and mildly harsh environments
• Bright uncoated finish maintains dimensional accuracy without coating-related tolerance buildup

Compatibility

Designed as a standard 3/8-16 UNC hex socket cap screw for use in any application specifying this thread size, drive type, and length under head in 18-8 stainless steel.

Installation Notes

Install using a 5/16 inch hex key or Allen-type driver. Ensure the mating tapped hole is clean and free of debris before threading. Apply appropriate anti-seize compound when installing stainless fasteners into stainless or aluminum tapped bores to prevent galling. Follow applicable mechanical and equipment manufacturer specifications for torque requirements.
