Value Collection 3TBT910C0308 Hex Cap Screw 5/8-11

Product Description

The VALUE COLLECTION 3TBT910C0308 is a fully threaded hex head cap screw designed for use in industrial, mechanical, and trade applications where corrosion resistance is a priority. Manufactured from Grade 316 stainless steel, this fastener offers superior resistance to chlorides, salt spray, and chemical exposure compared to standard 304 stainless. The screw measures 5/8-11 thread size with a 3-1/2 inch length under head and follows the Unified National Coarse (UNC) thread standard. It ships uncoated, preserving the natural corrosion resistance of the 316 alloy. Suitable for plumbers, pipefitters, HVAC technicians, and general maintenance trades working in corrosive or wet environments.

This fastener is well suited for outdoor structural connections, marine-adjacent installations, chemical plant equipment, pool and spa mechanical assemblies, and piping system flanges where standard steel fasteners would corrode prematurely. The fully threaded shank provides consistent clamping force along the full length of the fastener, making it appropriate for through-bolting applications where a nut is used on the opposite end. It is sold individually with a minimum order quantity of one piece.

Key Features

• Grade 316 stainless steel construction for high corrosion resistance in chloride and chemical environments
• Fully threaded shank along the entire 3-1/2 inch length under head
• 5/8-11 UNC thread form for compatibility with standard inch-system nuts and tapped holes
• Uncoated finish preserves the inherent corrosion resistance of the 316 alloy
• Weighs approximately 0.3 pounds per piece

Compatibility

Designed for use with standard 5/8-11 UNC hex nuts, washers, and tapped holes in inch-measurement fastening applications.

Installation Notes

Installation should be performed by a qualified tradesperson using a properly sized wrench or socket for the hex head drive. Always verify thread engagement depth and ensure mating threads are clean and free of debris before assembly. In corrosive or submerged environments, apply an appropriate anti-seize compound compatible with stainless steel to prevent galling during tightening. Do not use impact tools at excessive torque settings, as stainless steel fasteners are susceptible to galling and thread damage under high rotational speed.
