Value Collection R57001224 Hex Head Cap Screw 3/8-16

Product Description

The VALUE COLLECTION R57001224 is a hex head cap screw designed for general fastening applications in mechanical, industrial, and trade service environments. It features a 3/8-16 UNC thread profile with a 4.25-inch length under head and is manufactured from 18-8 stainless steel, providing corrosion resistance suitable for wet, coastal, or chemically exposed settings. The screw is partially threaded, meaning a portion of the shank below the head is smooth, which aids in clamping and alignment of joined materials. Supplied uncoated, the natural stainless finish is ready for installation without additional surface preparation.

This fastener is used across a wide range of applications including HVAC equipment mounting, plumbing fixture attachment, electrical enclosure assembly, pool equipment installation, and general mechanical assembly. The 3/8-16 UNC thread is a standard coarse-thread specification common in bolted joint assemblies throughout commercial and residential trade work. Partial threading makes it well suited for through-bolt applications where grip length and shank bearing are important to joint integrity.

Key Features

• 3/8-16 UNC coarse thread for broad compatibility with standard nuts and tapped holes
• 4.25-inch length under head accommodates deeper stack-ups and through-bolt applications
• 18-8 stainless steel construction resists corrosion in wet, outdoor, and chemically exposed environments
• Partially threaded shank improves clamping force and aids material alignment
• Uncoated finish — no additional prep required before installation
• Inch measurement system, length measured under head

Compatibility

Designed as a standard 3/8-16 UNC hex head cap screw compatible with any application requiring an inch-series coarse-thread fastener of this diameter and length in 18-8 stainless steel.

Installation Notes

Install using a standard hex socket or open-end wrench sized for a 3/8-inch hex head cap screw. Ensure mating threads in nuts or tapped holes are clean and free of debris before driving. Apply thread lubricant or anti-seize compound if the assembly will be exposed to prolonged moisture or dissimilar metals to prevent galling, which is common with stainless fasteners. Torque to the specification required by the equipment manufacturer or applicable mechanical code for the joint class.
