Value Collection 3107 Hex Cap Screw 1/2-13 X 2.5 in 316 Ss

Product Description

The VALUE COLLECTION 3107 is a fully threaded hex head cap screw designed for fastening applications that demand corrosion resistance and reliable clamping force. Built to DIN 933 standards, this fastener features a 1/2-13 UNC thread and measures 2-1/2 inches under the head. The Grade 316 stainless steel construction provides strong resistance to chlorides, saltwater, and chemical exposure, making it well suited for demanding environments. The uncoated finish maintains the inherent properties of the 316 alloy without added surface treatments. Licensed tradespeople and industrial maintenance technicians use this screw wherever thread integrity and corrosion resistance are both required.

This fastener sees wide use in plumbing, marine, food processing, chemical processing, and HVAC installations where exposure to moisture or corrosive agents is a concern. Its UNC thread pattern and 1/2-13 size are common in equipment assemblies, flanges, pipe supports, and structural connections across residential and commercial applications. The fully threaded shank provides maximum thread engagement throughout the clamped joint, which is important in applications requiring even load distribution.

Key Features

• Grade 316 stainless steel construction for high corrosion resistance including chloride and saltwater environments
• Fully threaded shank conforms to DIN 933 standard for consistent thread engagement
• 1/2-13 UNC thread size for broad compatibility with standard American inch fastener hardware
• 2-1/2 inch length under head suits medium-depth clamping and structural connections
• Uncoated finish preserves the natural corrosion resistance of 316 alloy without additional treatment

Compatibility

Designed as a standard UNC inch-series hex head cap screw compatible with 1/2-13 threaded holes, nuts, and inserts across industrial, plumbing, and mechanical assemblies conforming to DIN 933 specifications.

Installation Notes

Installation is typically performed by maintenance technicians, plumbers, or mechanical contractors using a standard hex wrench or socket set sized for a 1/2-13 fastener. Always ensure mating threads are clean and free of debris before installation. De-energize or depressurize any system before replacing or tightening fasteners in live assemblies. Avoid mixing 316 stainless fasteners with dissimilar metals in wet environments to minimize the risk of galvanic corrosion.
