Value Collection SC08230922 Arbor Nut 1-1/4-12 Alloy Steel

Product Description

The VALUE COLLECTION SC08230922 is a machine tool arbor nut designed for securing cutting tools and arbor assemblies on milling machines. Manufactured from alloy steel, this nut provides the strength and wear resistance required in demanding machining environments. It features a 1-1/4-12 unified fine thread form with right-hand thread direction, ensuring positive engagement under cutting loads. The fine thread pitch supports precise clamping force and reduces the risk of loosening during operation. At 0.05 pounds, it is a compact, single-piece hardware component suited for maintenance and tooling setups in machine shop environments.

This arbor nut is intended for use with milling machine arbors in standard machine shop applications. It is commonly installed during tooling changes, arbor assembly, or preventive maintenance on horizontal and vertical milling machines. The 1-1/4-12 thread size is a widely used standard on arbors designed to accept shell end mills, milling cutters, and similar tooling. Machinists, tool-and-die workers, and machine maintenance technicians are the primary installers of this component.

Key Features

• 1-1/4-12 unified fine thread for precise clamping engagement
• Right-hand thread direction for standard arbor installations
• Alloy steel construction for strength and wear resistance in machining environments
• Compact, lightweight design at 0.05 pounds
• Sold as a single unit, compatible with standard milling machine arbor assemblies

Compatibility

Designed for use with milling machine arbors requiring a 1-1/4-12 right-hand thread arbor nut.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician. Always power down and lock out the milling machine before removing or installing arbor components. Hand-tighten the nut onto the arbor thread before applying a spanner wrench to achieve final torque. Inspect arbor threads for damage or contamination before installation to ensure proper seating and clamping force.
