Material

High-resilience polypropylene based (PP) technopolymer, black colour, matte finish.

Fluted rim

""Soft-touch"" thermoplastic elastomer (TPE) chemically bonded, hardness 70 Shore A. The coating material is certified according to FDA (U.S. Food and Drug administration).

Standard executions

• MBT-B-SOFT: brass boss, threaded and plain blind hole.
• MBT-p-SOFT: zinc-plated steel threaded stud, chamfered flat end according to UNI 947 : ISO 4753 (see Technical data).

Features and applications

The rim, coated with ""soft-touch"" elastomer, improves the grip even in the presence of oils, greases and sweat from the hand. For this reason these fluted knobs are suitable for fitness machines, tools and machines for gardening and goods transport, high-precision instruments and disability aids.

Ergonomy and design

This kind of knob allows operation in an ergonomic way in all working conditions, reaching the maximum torque level with little fatigue for the operator's hand.

The very fine pitch structure of the rim, together with the soft-touch cover, simplifies the adjustement of the knob during rapid rotation (or screwing) without any unpleasant angular work for the hand and wrist.
