Ruland left hand threaded collars feature double tapped threads and tight face-to-bore perpendicularity.

Ruland has expanded its offering of threaded shaft collars by adding inch and metric left hand threaded styles. They are available in one- and two-piece clamp styles in steel and stainless steel with bore sizes ranging from 1/8 inch to 2-1/4 inches and 4mm to 30mm. The collars feature double tapped threads and tightly controlled face-to-bore perpendicularity (TIR ≤ 0.002 inch or 0.05mm). According to the company, forged screws test beyond industry standards to ensure maximum holding power. Left hand threaded collars are manufactured from 1215 lead-free steel with a proprietary black oxide finish and 303 stainless steel with hardware of like material. All Ruland products, distributed by RotoPrecision in Canada, are RoHS3 and REACH compliant.
