Value Collection SNI2150-010BX Slotted Hex Lock Nut 1-1/2-6

Product Description

The VALUE COLLECTION SNI2150-010BX is a slotted hex lock nut designed to resist loosening under vibration and dynamic loading. Manufactured from Grade 2 steel with a bright, uncoated finish, it features a 1-1/2-6 UNC right-hand thread profile. The nut measures 1-9/32 inches high with a 2-1/4-inch width across flats, making it suited for heavy fastening applications in mechanical assemblies. A slotted design allows a cotter pin or safety wire to be used for positive locking. Licensed tradespeople and maintenance technicians working on structural, industrial, or mechanical equipment will find this nut a standard-duty solution for secure fastening.

This slotted hex lock nut is appropriate for use in industrial machinery, structural assemblies, and general mechanical applications where a large-diameter UNC thread fastener is required. The 1-1/2-6 thread size places it in the heavy-duty fastener category, typically found in fabrication shops, maintenance facilities, and field service environments. Its bright uncoated finish is suited for dry or sheltered installations where corrosion resistance is not a primary concern.

Key Features

• Slotted design accepts cotter pin or safety wire for positive locking against vibration
• 1-1/2-6 UNC right-hand thread for compatibility with standard inch-series fastener systems
• Grade 2 steel construction provides reliable strength for general-duty applications

• Inch measurement system conforming to UNC fastener standards

Compatibility

Designed as a standard replacement or new-installation slotted hex lock nut for 1-1/2-6 UNC inch-series threaded fastener applications in general industrial and mechanical assemblies.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using an appropriate open-end or box wrench sized for a 2-1/4-inch across-flats engagement. Always confirm thread engagement depth and alignment before final torquing. For slotted nut applications, insert a properly sized cotter pin through the aligned slot and bolt hole after tightening to complete the locking method. Follow applicable industry or equipment manufacturer torque guidelines for the specific assembly.
