Value Collection 3TBT904C0208 Hex Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 3TBT904C0208 is a fully threaded hex head cap screw sized at 1/4-20 x 2-1/2 inches, manufactured from Grade 316 stainless steel with a bright uncoated finish. It follows the Unified National Coarse (UNC) thread standard and is measured by length under head. Grade 316 stainless steel offers elevated resistance to corrosion and chloride exposure compared to Grade 304, making this fastener a practical choice in wet, marine, chemical, or outdoor service environments. It is installed using a standard hex wrench or socket driver and is suited for general mechanical assembly, structural connections, and equipment fabrication where corrosion resistance is a priority.

This cap screw is used across a wide range of trade and industrial applications including HVAC equipment mounting, plumbing fixture attachment, pool and spa equipment assembly, and general structural fastening where stainless hardware is specified. Its fully threaded shank provides consistent thread engagement along the entire length under head, which is useful in thin-material or through-bolt applications. The 1/4-20 UNC thread size is one of the most commonly specified inch-series fastener sizes in mechanical and trade work.

Key Features

• Grade 316 stainless steel construction provides superior corrosion and chloride resistance
• Fully threaded shank for maximum thread engagement in through-bolt and thin-material applications
• 1/4-20 UNC thread standard, widely compatible with standard inch-series nuts and tapped holes
• Bright uncoated finish maintains dimensional accuracy and is suitable for direct use without additional treatment
• Hex head drive accepts standard hex wrenches and socket drivers

Compatibility

Designed for use with standard 1/4-20 UNC inch-series nuts, washers, and tapped components in mechanical assembly, HVAC, plumbing, pool, and general industrial applications.

Installation Notes

Installation is performed with a standard hex wrench, socket, or nut driver sized for a 1/4-inch hex head fastener. Disconnect power or shut off relevant systems before fastening into live equipment enclosures or pressurized assemblies. Avoid mixing stainless fasteners with dissimilar metals in submerged or highly conductive environments without appropriate isolation, as galvanic corrosion may occur. Follow applicable mechanical and structural codes for fastener torque and spacing requirements.
