Value Collection R57001065 Hex Socket Cap Screw 3/8-24 Unf

Product Description

The VALUE COLLECTION R57001065 is a hex socket cap screw designed for precision fastening in mechanical, structural, and industrial assembly applications. It features a 3/8-24 UNF thread, indicating a fine-pitch unified national thread form suited for applications requiring tight tolerances and strong clamping force. The fastener measures 5 inches in length under the head and is driven with a 5/16-inch hex key. Constructed from 18-8 stainless steel with a bright, uncoated finish, it provides corrosion resistance without additional surface treatment. Licensed trades and maintenance technicians commonly install this type of fastener in equipment assemblies, frames, and mounting hardware.

This screw is appropriate for use in residential and commercial mechanical systems where a fine-thread, high-strength stainless fastener is required. The 3/8-24 UNF thread pitch is commonly used in precision equipment, pump assemblies, HVAC component brackets, and other applications where vibration resistance and controlled torque engagement are priorities. The 18-8 stainless steel construction makes it suitable for environments with moderate moisture exposure or where galvanic compatibility with stainless hardware is required.

Key Features

• 3/8-24 UNF fine-thread form for high clamping force and vibration resistance
• 5-inch length under head for deep engagement in thick materials or stacked assemblies
• 5/16-inch hex drive for use with standard Allen or hex key sets
• 18-8 stainless steel construction provides corrosion resistance without a coating
• Bright, uncoated finish — no plating to flake or degrade under mechanical stress
• UNSPSC Code 31161501 for procurement system compatibility

Compatibility

Designed as a standard 3/8-24 UNF hex socket cap screw for use in any application calling for this thread size, drive type, and length specification. Confirm thread pitch, material grade, and length requirements against the equipment service manual before installation.

Installation Notes

Install using a properly sized 5/16-inch hex key or socket driver; do not use an undersized driver that may round the socket. Verify thread engagement depth and confirm the mating thread is also 3/8-24 UNF before fastening. Follow equipment manufacturer torque specifications — do not rely on feel alone for critical joints. Power down or de-energize any system before accessing fastened components in electrical or HVAC enclosures.
