Value Collection 199715 Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION 199715 is a partially threaded hex socket cap screw designed for secure fastening in structural and mechanical assemblies. The screw features a 5/16-18 UNC thread size and measures 2 inches in length under the head. It is driven with a 1/4 inch hex key, making it compatible with standard Allen wrenches and hex bit sets. Constructed from 18-8 stainless steel, the fastener offers solid corrosion resistance in wet, outdoor, and chemically exposed environments. This part is sold individually, with a minimum order quantity of 10 pieces.

This cap screw is suited for general-purpose mechanical and structural fastening applications across a wide range of industries including HVAC, plumbing, electrical enclosures, and equipment manufacturing. The partially threaded shank provides a bearing surface that resists shear loads, making it appropriate for bolted joint applications where a clamp load across unthreaded shank length is desirable. Licensed tradespeople and maintenance technicians commonly specify 18-8 stainless fasteners for installations where moisture or mild chemicals are present.

Key Features

• 5/16-18 UNC thread for broad compatibility with standard tapped holes and nuts
• 2 inch length under head suits medium-depth fastening applications
• 1/4 inch hex drive works with standard Allen keys and hex bit sockets
• Partially threaded shank provides a shear-resistant bearing surface
• 18-8 stainless steel construction delivers corrosion resistance in wet and outdoor environments

Compatibility

Designed as a standard 5/16-18 UNC hex socket cap screw for use in any application requiring that thread size and a 2 inch partially threaded stainless steel fastener.

Installation Notes

Install using a 1/4 inch hex key or hex bit driver. Ensure the tapped hole or mating nut matches the 5/16-18 UNC thread specification before installation. Apply appropriate thread lubricant or anti-seize compound if installing in environments prone to galling, which is common with stainless steel fasteners. Torque to values specified by the equipment manufacturer or applicable structural codes for 5/16-18 fasteners.
