Value Collection 30632 Hex Lock Nut 316 Ss Nylon Insert 50pk

Product Description

The VALUE COLLECTION 30632 is a hex lock nut with a nylon insert locking style, manufactured from Grade 316 stainless steel. It features a right-hand UNC thread direction and is designed to resist loosening caused by vibration and torque. The nylon insert compresses against mating threads to create a prevailing torque lock without requiring adhesives or secondary locking hardware. At 15/64 inches in height with a 11/32 inch width across flats, this is a compact fastener suited for corrosion-resistant applications in marine, plumbing, chemical, and food-service environments. Each package contains 50 nuts. Licensed contractors, pipefitters, and mechanical technicians are the typical installers of this hardware.

This nylon insert hex lock nut is suited for use in applications where vibration resistance and corrosion resistance are both required. Grade 316 stainless steel offers superior resistance to chlorides and saltwater compared to Grade 304, making it a common choice for marine hardware, pool equipment, coastal HVAC installations, and corrosive plumbing environments. The UNC thread standard ensures compatibility with standard inch-system fasteners across a wide range of assemblies. Sold in a package of 50 units, it is appropriate for both service-call quantities and small-project stocking.

Key Features

• Nylon insert locking style provides vibration-resistant prevailing torque without adhesives
• Grade 316 stainless steel construction for superior corrosion resistance in chloride and saltwater environments
• Right-hand UNC thread direction matches standard inch-system fastener assemblies
• Compact profile: 15/64 inches high, 11/32 inches width across flats
• Package quantity of 50 nuts per order unit

Compatibility

Designed as a standard UNC inch-system hex lock nut for use in general mechanical, plumbing, marine, and corrosion-resistant fastening applications where a nylon insert prevailing torque nut is specified.

Installation Notes

Installation is performed with a standard hex wrench or nut driver sized to 11/32 inches across flats. Always de-energize or depressurize the assembly before servicing fastened components. The nylon insert is single-use by design — once fully torqued and removed, the locking element may not retain full prevailing torque on reinstallation, and replacement is recommended. Follow applicable mechanical or plumbing codes for fastener torque requirements specific to the assembly being serviced.
