Value Collection R57001236 Hex Head Cap Screw 3/8-24

Product Description

The VALUE COLLECTION R57001236 is a hex head cap screw designed for fastening applications that demand corrosion resistance and dimensional precision. Built to inch-system standards, this screw features a 3/8-24 UNF (Unified Fine) thread and measures 4.5 inches under the head. The partially threaded shank allows the unthreaded portion to bear shear loads while the threaded section grips the mating material. Manufactured from 18-8 stainless steel and left uncoated, it is well suited to environments where rust resistance matters without adding plating thickness that could affect fit.

This fastener is used in mechanical assembly, equipment fabrication, and maintenance applications across a range of trades. The fine thread pitch of the 3/8-24 designation provides stronger thread engagement compared to coarse-thread equivalents of the same diameter, making it appropriate for applications requiring precise torque control or resistance to vibration loosening. It is commonly installed in HVAC equipment, pump housings, piping supports, pool equipment enclosures, and general structural assemblies where stainless hardware is specified.

Key Features

• 3/8-24 UNF fine thread for high thread-engagement strength and vibration resistance
• 4.5-inch length under head accommodates deep fastening applications
• Partially threaded shank carries shear loads on the unthreaded section
• 18-8 stainless steel construction provides corrosion resistance in wet or humid environments
• Uncoated finish maintains consistent dimensional tolerances without plating variables

Compatibility

Designed as a standard inch-system hex head cap screw compatible with any 3/8-24 UNF tapped hole or hex nut of the same thread specification.

Installation Notes

Installation is performed with a standard hex wrench or socket sized to the 3/8-inch hex head. Always ensure the mating thread is 3/8-24 UNF before driving to avoid cross-threading. Power down or de-energize any equipment and relieve fluid pressure before replacing fasteners on live systems. Avoid mixing stainless steel fasteners with dissimilar metals in submerged or high-moisture assemblies to minimize galvanic corrosion risk.
