Value Collection 208956B Hex Head Cap Screw 3/8-16 X 4 in

Product Description

The VALUE COLLECTION 208956B is a 3/8-16 hex head cap screw measuring 4 inches under the head, manufactured from 18-8 stainless steel with a unified national coarse (UNC) thread form. The 9/16-inch hex drive accepts standard hex wrenches and sockets. The 18-8 stainless steel construction provides corrosion resistance suitable for general industrial, mechanical, and trade applications. This fastener is used by plumbers, HVAC technicians, electricians, and general contractors wherever a corrosion-resistant, full-thread hex cap screw is required in structural or equipment-mounting assemblies.

This screw is suited for light to medium fastening tasks in environments where moisture or chemical exposure makes carbon steel fasteners a poor choice. Typical applications include equipment panels, pipe hangers, mechanical enclosures, pool equipment mounting, and outdoor or wet-area installations. The inch-series 3/8-16 thread is one of the most common coarse-thread sizes in North American mechanical systems, making this fastener broadly usable across HVAC, plumbing, electrical, and pool service work.

Key Features

• 18-8 stainless steel construction for corrosion resistance in wet and outdoor environments
• 3/8-16 UNC thread — standard coarse inch-series thread for broad compatibility
• 4-inch length under head suits deep-reach fastening and thick-stack assemblies
• 9/16-inch hex drive fits common wrenches and sockets standard in trade toolkits
• Inch measurement system — direct fit for North American equipment and hardware

Compatibility

Designed for use in any application requiring a 3/8-16 UNC hex head cap screw in 18-8 stainless steel. Consult equipment manufacturer documentation to confirm thread size, length, and material requirements before installation.

Installation Notes

Install using a 9/16-inch open-end, box-end, or socket wrench. Ensure mating threads are clean and free of debris before driving. In stainless-to-stainless thread applications, apply an anti-seize compound to reduce the risk of galling. Power down or de-energize any equipment before accessing fastened panels or enclosures.
