Value Collection R57001234 Hex Head Cap Screw 3/8-24

Product Description

The VALUE COLLECTION R57001234 is a partially threaded hex head cap screw sized 3/8-24 with a 3.5-inch length under head, manufactured from 18-8 stainless steel with an uncoated finish. The 3/8-24 designation indicates a 3/8-inch nominal diameter with 24 threads per inch, conforming to the Unified National Fine (UNF) thread standard. The 18-8 stainless steel construction provides corrosion resistance suitable for general industrial, mechanical, and trade applications. Partial threading leaves the shank smooth near the head, which helps align mating components and reduces thread engagement in applications where full threading is not required.

This fastener is used across a wide range of trade and mechanical assemblies where fine-thread engagement and corrosion resistance are priorities. Common applications include HVAC equipment mounting, plumbing fixture attachment, electrical enclosure assembly, and general mechanical fabrication. The fine UNF thread pitch provides higher tensile strength and better resistance to loosening under vibration compared to coarse-thread equivalents of the same diameter. Suitable for use in both indoor and outdoor environments where stainless steel is specified.

Key Features

• 3/8-24 UNF thread standard — fine pitch for improved vibration resistance and higher clamp load
• 3.5-inch length under head for deeper reach in thick or layered assemblies
• Partial threading preserves smooth shank near head for alignment and load-bearing fitment
• 18-8 stainless steel construction resists corrosion in wet or chemically active environments
• Uncoated finish — no plating to compromise dimensional tolerance or introduce galvanic concerns

Compatibility

Designed for use in any assembly specifying a 3/8-24 UNF partially threaded hex head cap screw in 18-8 stainless steel. Verify thread engagement depth and clearance hole dimensions against assembly drawings before installation.

Installation Notes

Installation is performed by mechanical and trade technicians using standard hex wrenches or socket drives sized for a 3/8-inch hex head cap screw. Always confirm mating thread material compatibility with 18-8 stainless steel to avoid galling — apply anti-seize compound to the threads when fastening into stainless or aluminum tapped holes. Torque to the value specified in the applicable equipment service documentation; do not estimate torque values without a reference specification. Follow applicable mechanical and equipment codes for the installation environment.
