برغي صقل 1/4 × 1/8 (طول إجمالي 1 1/2 بوصة)

Threads right onto my arbor without any wobble, and the 1 1/2" length gives just enough reach for tight spots on the buffer. I've already swapped it between two wheels and it's held up fine.

The threads on this 1/4" buff screw bit into the wheel cleanly and hold tight even at high speeds. Its 1 1/2 inch overall length gave me just enough clearance to mount everything without bottoming out. Exactly what I needed to get my setup running smoothly.

Works perfectly for securing buffing wheels on my bench grinder. The 1/4-20 thread size was exactly what I needed, and the 1 1/2 inch overall length gives just enough room to tighten by hand. Only wish the head was a bit wider for easier gripping with pliers.
