وصلة لولبية يمينية إلى مستدق D4257 مقاس 4 بوصات

Needed a 4-inch extension for my grinder and this splice fit perfectly — the right thread to taper design locked on without any wobble. Works exactly as described for adapting standard abrasive wheels.

The right-hand thread connection seated perfectly on my grinder arbor, and the 4-inch splice gave me the exact extension I needed without any wobble on the taper. I’ve already used it on two heavy jobs and it’s held up without loosening.

The threads on this 4-inch splice are machined cleanly, so it screws onto my spindle without any wobble. It saved me from having to buy an entirely new arbor for a specific job.
