1-3/8" O.D. Ball Knob - Yellow - 3/8-16 Female Threaded Brass Insert

Add a high visibility yellow knob instead of a boring black knob! The finish is more of a matte yellow than a super high gloss yellow. The female threads are cut into a brass insert for a tooling quality installation! There are many other non-fitness uses. You can install this knob on any male 3/8-16 threaded shaft for tooling, automotive, machinery, or decorative applications.

Features:

Outside diameter: 1-3/8" nominal/ 1.4" actual measured

Made of high-impact ABS

Replaces other standard 3/8-16 ball knobs

Thread: 3/8-16 Female Coarse Thread - most common thread for pop pins and weight stack pins

Thread Length: 5/8" approx

Insert is made of brass and embedded into knob - won't pull out during use - better than plastic threads

Make pop pins and weight stack pins really stand out with this high-visibility yellow knob!

Very rare and hard-to-find item anywhere, but as usual we carry them!
