Value Collection V70018PS 5/16-18 Hex Jam Nut 316 Stainless Steel

Product Description

The VALUE COLLECTION V70018PS is a 5/16-18 UNC hex jam nut manufactured from Grade 316 stainless steel with a bright, uncoated finish. Jam nuts are thin profile hex nuts used to lock a standard nut in place or to secure fastener assemblies where a full-height nut would interfere with clearance. The 316 stainless steel alloy provides strong resistance to corrosion, chlorides, and harsh chemicals, making this nut well-suited for demanding environments. It carries a right-hand thread direction and measures 1/2 inch across the flats with a height of 3/16 inch. Licensed tradespeople and maintenance mechanics across HVAC, plumbing, electrical, and pool equipment applications install this type of hardware as part of routine equipment assembly and repair work.

This jam nut is appropriate for use in residential and commercial applications where corrosion resistance is a priority, such as outdoor mechanical equipment, pool and spa installations, marine-adjacent environments, and anywhere exposure to moisture or chemicals is a concern. The 5/16-18 UNC thread size fits standard fractional fastener assemblies commonly found in equipment frames, mounting brackets, and pipe supports. This nut is sold individually per package with a minimum order quantity of 50 pieces.

Key Features

• Grade 316 stainless steel for superior corrosion and chemical resistance
• 5/16-18 UNC right-hand thread for compatibility with standard fractional fastener assemblies
• Jam nut profile at 3/16 inch height for use in low-clearance or lock-nut applications
• Bright, uncoated finish — no plating to chip, flake, or react with stainless fasteners
• 1/2 inch across flats — fits standard 1/2-inch hex wrench or socket

Compatibility

Designed for use with 5/16-18 UNC threaded fasteners in standard fractional thread assemblies. Verify thread pitch and fastener material before installation to ensure proper fit and galvanic compatibility.

Installation Notes

Installation is performed by mechanics, maintenance technicians, or trade professionals using a standard 1/2-inch hex wrench or socket. When used as a jam nut, thread the jam nut onto the fastener first, then thread the primary nut against it and torque both to lock the assembly. Avoid mixing stainless steel hardware with dissimilar metals in direct contact to minimize the risk of galvanic corrosion. Always inspect threads for damage before assembly.
