Value Collection 59NE8-182 Dn Hex Lock Nut 1-1/8-12 Grade 8

Product Description

The VALUE COLLECTION 59NE8-182 DN is a nylon insert hex lock nut designed to resist loosening under vibration and dynamic loading. Manufactured from Grade 8 steel with a bright, uncoated finish, this fastener meets UNF thread standards at a 1-1/8-12 thread size with right-hand threading. The nylon insert creates friction against the mating thread, maintaining clamp load without the need for adhesives or secondary locking hardware. At 1-11/64 inches in height with a 1-5/8-inch width across flats, it suits high-strength bolting applications where a standard hex nut would be insufficient. Installed by mechanics, millwrights, and maintenance technicians across industrial and heavy-equipment applications.

This nut is suited for high-torque, high-vibration environments where Grade 8 material strength is required. Typical applications include structural assemblies, heavy equipment frames, agricultural machinery, and industrial drivetrain components. The UNF thread designation makes it appropriate for fine-thread bolting scenarios where greater thread engagement and superior tensile load capacity are priorities over coarse-thread alternatives. The bright, uncoated finish is standard for indoor or protected installations where corrosion resistance is not a primary concern.

Key Features

• Nylon insert locking mechanism resists loosening from vibration without adhesives
• Grade 8 steel construction for high-strength bolting requirements
• 1-1/8-12 UNF right-hand thread for fine-thread applications
• 1-5/8-inch width across flats for standard hex wrench or socket fit
• Bright, uncoated finish suitable for protected or indoor installations
• Single-use locking element — nylon insert integrity is compromised after removal

Compatibility

Designed for use with Grade 8 or equivalent 1-1/8-12 UNF right-hand threaded fasteners in industrial, agricultural, or heavy-equipment assemblies.

Installation Notes

Installation requires a standard hex socket or open-end wrench sized for a 1-5/8-inch across-flats dimension. Power down or de-energize any equipment before accessing fastener locations on live machinery. Nylon insert lock nuts are considered single-use components — once removed from a fastener, the locking torque of the nylon insert is reduced and the nut should be replaced. Consult applicable equipment manufacturer torque specifications for the assembly being serviced.
