Value Collection SNFI2175-010BX Slotted Hex Lock Nut

Product Description

The VALUE COLLECTION SNFI2175-010BX is a slotted hex lock nut designed to maintain a secure, vibration-resistant fastening in heavy-duty mechanical and structural assemblies. Manufactured from Grade 2 steel with a bright uncoated finish, it meets UNF (Unified National Fine) thread standards at a 1-3/4-12 thread size. At 1.5 inches high and 2.625 inches across the flats, this nut is sized for large-diameter fastener applications where thread integrity and holding strength under load are critical. Licensed mechanics, millwrights, pipefitters, and industrial maintenance technicians are the typical installers.

This slotted lock nut is suited for applications requiring positive locking via a cotter pin or safety wire through the nut slots, such as axle assemblies, shaft retention, and heavy equipment linkages. The right-hand thread direction and UNF thread form make it compatible with standard fine-thread fastener systems common in automotive, agricultural, and industrial equipment. It is sold and packaged individually.

Key Features

• Slotted design accepts cotter pin or safety wire for positive anti-loosening retention
• 1-3/4-12 UNF right-hand thread for compatibility with standard fine-thread fastener systems
• Grade 2 steel construction provides reliable mechanical strength for general-duty applications
• Bright uncoated finish — suitable for indoor or protected environments
• 1.5 inches height and 2.625 inches across flats for large-diameter shaft and axle fitment

Compatibility

Designed as a standard UNF slotted hex lock nut for use with 1-3/4-12 fine-thread fastener assemblies in mechanical, industrial, and equipment maintenance applications.

Installation Notes

Installation is performed by qualified mechanics or maintenance technicians using an appropriately sized open-end or box wrench rated for the fastener torque required by the equipment manufacturer. Always consult the equipment service manual for the correct torque specification before tightening. Insert a cotter pin or safety wire through the slots and the mating bolt hole after torquing to complete the positive locking retention. Inspect threads for damage or contamination before installation and do not install on damaged or mismatched thread forms.
