    Specialty tools for your custom hardware.

    A must for any enthusiast.

    Doing the job right requires special tools, and these pieces from Notchead are a must-have! The custom Polishing Grip is perfect for polishing bolts and assorted small parts. The soft aluminum jaws grip the threads of your bolt firmly, but will not cause damage. This allows you to polish quickly and efficiently. The special pin-drive sockets are necessary when installing or removing your Notchead bolts. These replacements can be used with your choice of combination wrench or socket wrench.

    Polishing Grip - features two collets (1/4"-3/8" and #4 screw-1/4") Large Collet - Adjust from 1/2" to 7/16" Nut Polishing Attachment - Includes 4 sizes of coarse and fine thread adjustments (#10, 1/4", 5/16", 3/8") Sockets are available in several sizes depending on your bolt size.
