Value Collection 208967 Hex Head Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 208967 is a hex head cap screw threaded 3/8-16 UNC with a 5-inch length under head. Manufactured from Grade 18-8 stainless steel, it delivers solid corrosion resistance in wet, chemical-exposure, and outdoor environments. The 9/16-inch hex drive size is compatible with standard wrenches and sockets. This fastener is suited for mechanical assemblies, equipment mounting, and structural connections where a fully threaded or partially threaded hex cap screw is required. Licensed tradespeople and maintenance technicians across HVAC, plumbing, electrical, and industrial service work reach for Grade 18-8 stainless fasteners where carbon steel would corrode prematurely.

This hex head cap screw is used in a wide range of trade and industrial applications including equipment frames, junction box mounting, pipe hanger assemblies, and general mechanical fabrication. The 3/8-16 UNC coarse thread pattern is the standard for most inch-based hardware in North American trade work, providing reliable thread engagement in steel, aluminum, and plastic tapped holes. It is appropriate for both indoor and outdoor installations where moderate corrosion resistance is required.

Key Features

• 3/8-16 UNC coarse thread for broad compatibility with standard inch-series tapped holes
• 5-inch length under head accommodates deeper assemblies and thicker material stacks
• 9/16-inch hex drive works with standard open-end, box, and socket wrenches
• Hex head cap screw profile provides high torque transfer and reliable clamping force

Compatibility

Designed as a standard 3/8-16 UNC hex head cap screw suitable for any application requiring a 5-inch Grade 18-8 stainless steel fastener in inch-series threaded assemblies.

Installation Notes

Install using a 9/16-inch wrench or socket. Verify that mating threads are clean and free of debris before driving the screw to avoid cross-threading or galling, which is a known risk with stainless steel fasteners. Apply an appropriate anti-seize compound when threading stainless into stainless to prevent thread galling. Torque to the value specified by the equipment manufacturer or applicable structural standard.
