Value Collection SLFI8125CAD-015BX Hex Lock Nut 1-1/4-12

Product Description

The Value Collection SLFI8125CAD-015BX is a distorted-thread hex lock nut designed to resist loosening under vibration and dynamic loads. It is manufactured from Grade C steel with a clear cadmium finish that provides corrosion resistance in demanding service environments. The nut measures 1 inch high with a width across flats of 1-7/8 inches and is threaded to a 1-1/4-12 UNF right-hand specification. This fastener is appropriate for mechanical assemblies, industrial equipment, and structural connections where standard hex nuts present an unacceptable loosening risk. Licensed trades and industrial maintenance technicians are the primary installers.

This hex lock nut is suited for use in industrial machinery, heavy equipment, and mechanical assemblies that experience continuous vibration or cyclic loading. The distorted-thread locking mechanism provides prevailing torque without the need for secondary locking devices such as washers or adhesives. The 1-1/4-12 UNF fine thread series is common in applications requiring precise clamping force control or use in thinner-walled components. This nut is sold in single-unit quantity.

Key Features

• Distorted-thread locking style delivers prevailing torque resistance without additional hardware
• Grade C steel construction provides strength suitable for industrial fastening applications
• Clear cadmium finish offers corrosion protection in moderately harsh environments
• 1-1/4-12 UNF right-hand thread for compatibility with fine-thread fastener systems
• 1 inch height and 1-7/8 inch width across flats for standard hex tooling

Compatibility

Designed as an OEM-style replacement or maintenance fastener for mechanical assemblies using 1-1/4-12 UNF right-hand threaded studs or bolts requiring a prevailing-torque hex lock nut.

Installation Notes

Installation should be performed by qualified mechanical or maintenance technicians familiar with fastener torque requirements and locking hardware. De-energize and lock out all equipment before replacing fasteners in live assemblies. Use standard hex wrenches or sockets sized for 1-7/8 inch across flats. Do not reuse distorted-thread lock nuts after removal, as the locking mechanism may be compromised on reuse.
