Value Collection 30600 Hex Head Cap Screw 3/8-16 X 4 in

Product Description

The VALUE COLLECTION 30600 is a 3/8-16 UNC hex head cap screw measuring 4 inches under the head, manufactured from Grade 316 stainless steel with a partial thread pattern and no surface coating. Grade 316 stainless provides superior corrosion resistance compared to 304, making it a dependable choice in wet, chemical, or marine-adjacent environments. The hex drive head accepts standard wrenches and sockets used in general mechanical, industrial, and trade applications. This fastener is sold individually but requires a minimum order quantity of 50 pieces. It suits technicians and tradespeople who need reliable, corrosion-resistant fasteners for structural and mechanical assembly work.

This cap screw is suited for use in plumbing, HVAC equipment mounting, pool and spa equipment installation, electrical enclosure assembly, and general industrial fabrication where moisture or corrosive conditions are a factor. The partially threaded shank allows for clamping force across unthreaded material sections, which is common in flange bolting and equipment bracket applications. The UNC thread standard ensures compatibility with standard inch-pattern tapped holes and nuts.

Key Features

• Grade 316 stainless steel construction for strong corrosion resistance in harsh or wet environments
• 3/8-16 UNC thread size compatible with standard inch-pattern hardware
• 4-inch length under head with partial threading for effective clamping in flange and bracket assemblies
• Uncoated finish - no plating that could chip, flake, or compromise corrosion performance
• Hex head accepts standard open-end, box, or socket wrenches

Compatibility

Designed for use in standard 3/8-16 UNC tapped holes and with 3/8-16 hex nuts across industrial, mechanical, and trade assembly applications requiring inch-system fasteners.

Installation Notes

Installation should be performed by a qualified technician using an appropriately sized wrench or socket for the hex head. Always ensure the mating tapped hole or nut is clean and free of debris before threading to avoid galling, which is a known risk with stainless fasteners. Apply an anti-seize compound to the threads when joining stainless to stainless to reduce galling risk. Power down or de-energize any equipment before working on assemblies where this fastener secures electrical or mechanical components.
