Purpose and audience

This Climax Metal Products MC-40-S Metric Set Screw Collar is a transparent power-transmission component designed for mechanical assemblies that require a secure locking collar. It suits maintenance engineers and hobbyists working with metric shafting who need a reliable, ready-to-use collar without additional machining.

Build integration

The collar fits directly onto metric shafts and uses a set-screw locking method, so no keyways, threading or specialised tools are required during installation. Its transparent finish allows visual confirmation of shaft engagement and screw contact, freeing the builder from guesswork when positioning the component in tight assemblies.

Sustained-load behaviour

Under continuous operation the set-screw maintains clamping force without the relaxation sometimes seen in friction-only collars, keeping the mounted component fixed through vibration and thermal cycling. The product carries a California Proposition 65 notice for chemicals linked to cancer and reproductive harm, so handlers should follow standard workshop hygiene during prolonged use.

Questions about this item

What is the 40 mm bore limit that determines shaft fit under sustained load?

The MC-40-S collar has a 40 mm bore designed for metric shafts; the set screw clamps directly on the shaft surface to resist axial movement during continuous operation.

How much heat or noise does the MC-40-S generate when the shaft runs all day?

The collar itself produces no heat or noise; any temperature rise or sound comes from the shaft and bearings, not from the steel collar or its set screw.

Which hex key size must I already own to tighten the set screw on the MC-40-S?

A 4 mm hex key is required to secure the M5 set screw on this 40 mm metric collar.
