Value Collection 207688C Hex Head Cap Screw 3/8-16 X 1-1/4 in

Product Description

The VALUE COLLECTION 207688C is a hex head cap screw designed for fastening applications that require corrosion resistance and dimensional reliability. Manufactured from 18-8 stainless steel, this fastener features a 3/8-16 UNC thread and measures 1-1/4 inches under the head. The 9/16-inch hex drive accepts standard hex wrenches and sockets. It is suited for mechanical assemblies, equipment fabrication, and service work where moisture, chemicals, or outdoor exposure are factors. Licensed tradespeople in HVAC, plumbing, electrical, and general mechanical trades encounter this fastener in panel mounting, bracket installation, and equipment support structures.

This screw is used in residential and commercial trade applications where a standard inch-series UNC fastener is required. The 3/8-16 thread size is common in equipment frames, access panels, strut channel assemblies, and general structural connections. The 18-8 stainless steel grade performs well in wet environments including mechanical rooms, rooftop equipment, pool equipment enclosures, and coastal installations where carbon steel fasteners would corrode prematurely.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet and outdoor environments
• 3/8-16 UNC thread is a widely used inch-series coarse thread for strong clamping force
• 1-1/4 inch length measured under the head suits medium-depth fastening applications
• 9/16-inch hex drive is compatible with standard hex wrenches and impact sockets
• Inch measurement system with UNC thread standard ensures broad hardware compatibility

Compatibility

Designed as a standard inch-series UNC hex head cap screw for use in any application requiring a 3/8-16 x 1-1/4 inch stainless steel fastener.

Installation Notes

Install using a 9/16-inch hex wrench, box wrench, or socket driver. Verify thread engagement depth before torquing to ensure full thread contact with the mating material. Do not mix stainless steel fasteners with dissimilar metals in environments prone to galvanic corrosion without an appropriate barrier. Apply anti-seize compound when fastening into aluminum or other reactive materials to prevent galling common to stainless steel threads.
