American Sanders Nut 5/16"-18 Hex Jam – Precision Fastening for Sanding Equipment
Secure Your Floor Sander Components with Confidence

The American Sanders 5/16"-18 Hex Jam Nut is a specialized fastening component used in various American Sanders machines to provide a low-profile, secure hold where space is limited or dual-nut locking is required. Its precision threading and hexagonal shape make it ideal for maintaining tightness on assemblies subject to heavy vibration during floor sanding.

Key Features:

• Thread Size: 5/16"-18 (coarse thread)

• Hex Jam Design: Thinner than standard nuts for tight-clearance applications or locking against another nut.

• Durable Steel Construction: Built to withstand heavy use in commercial and residential sanding environments.

• Corrosion-Resistant Finish: Helps extend lifespan, even in dusty, high-friction conditions.

Common Uses:

• Wheel assemblies

• Caster and handle mounts

• Vibration-prone joints

• Motor and drum retention hardware on models like the Super 7, B2 Edger, and Classic 8

Why It Matters:

This nut is designed for secure fastening in high-performance sanding equipment where vibration and torque can easily loosen standard nuts. Its jam-style profile allows you to lock it in place using a second nut or fit it into confined mechanical assemblies.

Pro Tip for Contractors and Technicians:

Always replace worn or rounded nuts with OEM-grade parts like this Hex Jam Nut to maintain torque integrity and prevent loosening during operation. Use a thread locker in high-stress areas for extra security.
