Holo-krome 78102 Hex Socket Cap Screw 3/8-16 Unc

Product Description

The HOLO-KROME 78102 is a hex socket cap screw designed for secure fastening in applications where a recessed drive is required for clearance or torque control. It features a 3/8-16 UNC thread size, a 5/16-inch hex drive, and a 1-1/2-inch length under head. The screw is fully threaded and manufactured from 18-8 stainless steel with a bright, uncoated finish, providing solid corrosion resistance for general industrial and mechanical assembly work. It meets ASME B18.3 and ASTM F837 fastener standards, making it a reliable choice for precision assemblies in demanding environments.

This fastener is suited for use in mechanical, industrial, and light structural assemblies where a socket head cap screw is specified. The 3/8-16 UNC thread is a common coarse-thread standard used across a wide range of equipment and machinery. The 18-8 stainless steel construction makes it appropriate for environments with moderate moisture or chemical exposure. Licensed trades and maintenance professionals working on equipment panels, pump housings, HVAC brackets, and similar hardware will find this a straightforward replacement or new-installation fastener.

Key Features

• 3/8-16 UNC coarse thread for broad compatibility with standard tapped holes
• Fully threaded shank for maximum thread engagement across the full 1-1/2-inch length
• 5/16-inch hex socket drive for use with standard Allen or hex key sets
• 18-8 stainless steel construction for corrosion resistance in wet or outdoor-adjacent applications
• Bright, uncoated finish meets ASME B18.3 and ASTM F837 standards

Compatibility

Designed as an OEM-style replacement or standard installation fastener for any application requiring a 3/8-16 UNC hex socket cap screw with a 1-1/2-inch length under head.

Installation Notes

Installation is performed using a 5/16-inch hex key or Allen wrench. Power down or de-energize any equipment before fastener service where electrical components are present. Follow applicable ASME or equipment manufacturer torque guidelines for 3/8-16 fasteners in the target material. Do not mix stainless steel fasteners with dissimilar metals in environments prone to galvanic corrosion without appropriate isolation.
