Value Collection 1-THN-10C Hex Lock Nut Nylon Insert

Product Description

The VALUE COLLECTION 1-THN-10C is a nylon-insert hex lock nut machined from 18-8 stainless steel with an uncoated finish. The nylon insert creates interference with the mating thread, resisting loosening caused by vibration and dynamic loads without requiring a secondary locking device. The nut measures 3/16 inches in height with a 3/8-inch width across flats and a width across points of 0.410 inches. Thread direction is right hand, and the fastener is dimensioned to the UNC (Unified National Coarse) standard. This part is sold individually, with a minimum order quantity of 100 units.

This hex lock nut is suited for general mechanical assembly, HVAC equipment mounting, plumbing support structures, electrical enclosures, and other applications where stainless steel corrosion resistance is required alongside reliable vibration-resistant fastening. The 18-8 stainless steel construction makes it appropriate for both indoor and outdoor installations subject to moisture or mild chemical exposure. Electricians, HVAC technicians, plumbers, and maintenance trades all use this type of hardware regularly on equipment frames, brackets, and panel assemblies.

Key Features

• Nylon insert locking style resists loosening under vibration without secondary hardware
• 18-8 stainless steel construction provides corrosion resistance in wet or outdoor environments
• Uncoated finish — no added coatings that could interfere with electrical grounding paths or chemical compatibility
• Right hand thread, UNC fastener standard for broad compatibility with standard inch-series fasteners
• Width across flats of 3/8 inches fits standard 3/8-inch drive and open-end wrenches

Compatibility

Designed as a standard UNC inch-series nylon-insert hex lock nut suitable for use with any compatible right-hand-thread UNC male fastener of the matching nominal thread size.

Installation Notes

Installation of hex lock nuts is typically performed by maintenance and trade professionals as part of equipment assembly or field service work. De-energize or shut down any system before replacing fasteners on live equipment. Use a properly sized wrench matching the 3/8-inch width across flats to avoid rounding the nut. Nylon-insert lock nuts are generally intended for single-use applications — reuse after removal may reduce the locking torque of the nylon insert.
