Value Collection R57001066 Hex Socket Cap Screw 3/8-24

Product Description

The VALUE COLLECTION R57001066 is a hex socket cap screw designed for precision fastening applications requiring a fine-thread profile and corrosion-resistant construction. This screw features a 3/8-24 UNF thread size, a 6-inch length under head, and a 5/16-inch hex drive. It is manufactured from 18-8 stainless steel with a bright, uncoated finish. The combination of fine UNF threading and stainless construction makes this fastener well suited for mechanical assemblies, fluid system components, and equipment subject to moisture or chemical exposure. Licensed tradespeople and industrial maintenance technicians are the typical installers.

This cap screw is used across a wide range of commercial and industrial applications where a recessed hex drive provides torque advantage in confined spaces. The 3/8-24 UNF thread specification is common in precision mechanical assemblies, HVAC equipment mounting, plumbing fixture hardware, and general machine component fastening. The 6-inch length under head accommodates thicker material stacks or deeper threaded engagement requirements. This fastener ships as a single-piece unit.

Key Features

• 3/8-24 UNF fine thread for precise engagement and vibration resistance
• 6-inch length under head for deep material stack or long threaded engagement
• 5/16-inch hex socket drive for use with standard hex keys or socket drivers
• 18-8 stainless steel construction for corrosion resistance in wet or chemical environments
• Bright, uncoated finish — no plating to flake or interfere with thread tolerances

Compatibility

Designed as a standard 3/8-24 UNF hex socket cap screw suitable for threaded holes or nuts conforming to UNF inch-series specifications across general mechanical, industrial, and trade service applications.

Installation Notes

Installation is performed with a 5/16-inch hex key or hex socket driver. Confirm the mating thread is 3/8-24 UNF before installation to avoid cross-threading. De-energize or depressurize any system before removing or replacing fasteners in pressurized or live-electrical assemblies. Apply thread lubricant or anti-seize compound if required by the equipment manufacturer's service documentation.
