5/16"-18 Hex Speed Nuts 15PK

This pack contains fifteen coarse-thread hex speed nuts made from steel. They suit automotive, industrial and general repair tasks where quick hand tightening is needed. The 5/16"-18 thread pitch matches many standard bolts and studs. Buyers who want a reusable assortment for recurring jobs will find the quantity convenient.

Check thread pitch and diameter

Verify that the mating bolts or studs use a 5/16"-18 coarse thread before ordering. Confirm the material is suitable for the load and corrosion environment of your project. Ensure the hex flats can be accessed with the tools available in your workspace. Buyers who need fine-thread or metric fasteners cannot use this pack.

Fifteen-piece bulk pack

The fifteen-piece count reduces the need for frequent re-orders on repeat maintenance work. Having a dedicated pack keeps identical nuts together for consistent torque feel. No additional washers, lock features or driver bits are included in the package. Buyers who require locking nuts or smaller quantities must source them separately.
