Lever handle HS20 stem 36x86/M10x16 mm, fitting in galvanized steel, glossy black

Heavy levers need heavy grips. HS20 with a stud is the widest rotating lever handle in the family; the grip measures 86 mm in length and 36 mm in diameter at the base and is mounted on a threaded M10 stud in zinc plated steel. Since the grip rotates freely around the stud it follows the angle of the hand through the lever movement, and you avoid the sliding, chafing grip that fixed handles give on long movements.

The stud has a thread length of 16 mm, enough for full engagement in a steel lever arm without the joint bottoming out. The grip tapers from 36 mm at the base toward the top; the shape supports the palm when pulling and gives the fingers room when pushing. The surface is glossy black, easy to wipe clean and classic in appearance.

The choice of size is also a question of working posture. With a grip of this diameter the hand can work half open instead of clenched, which moves the load from the fingers to the whole palm; operators who pull the same lever hundreds of times a day usually feel the difference within a week. So do not be stingy with grip size on heavy controls.

The grip is injection molded in PA6, a nylon with high impact strength and good resistance to oils, greases and cutting fluids. The shade is colored all the way through; no paint layer can flake or wear off. The zinc layer on the steel stud protects against rust in a normal workshop environment, while wetter environments set higher demands and can justify another design.

This size belongs on levers where the operator pulls with the whole hand: rapid feeds on larger lathes, clamping levers on hydraulic and mechanical fixtures, control levers on presses and press brakes and controls on forestry and agricultural machines. We also see it on test rigs and test benches where levers are loaded hard and often. Where a smaller grip does the job there is HS10 with a stud; but when the force and the movement are large, the extra millimeters in diameter pay off.

Mounting consists of screwing the stud into a threaded M10 hole and tightening. Thread locker can be used freely since the joint is steel against steel and the liquid never reaches the plastic. Just check that the lever arm has at least 16 mm of thread depth, so that the stud gets full engagement.

Maintenance is in practice nonexistent. The bearing between grip and stud needs no lubrication, the plastic ages slowly indoors and there is no paint layer to touch up. If the machine runs three shifts the handle is rarely the component that gives up first; and the day it does happen, replacing it is a matter of unscrewing and screwing back on.

HS20 with a stud is stocked in the 36x86 mm design with an M10 thread. The same family includes HS20 with a plain hole for press fit and with a threaded bushing entirely in plastic, as well as the sister series HS10 and HS30 which together cover threads from M6 to M12. The manufacturer's standard pack holds 200 handles.

If you are weighing a fixed against a rotating grip in this size there is a simple rule of thumb. Levers with a short movement, such as clamp levers and position selectors, work well with a fixed handle; levers with a long sweeping movement, such as feeds and cranks, always do best with a rotating one. The length of the movement decides how much the hand otherwise has to slide against the grip, and it is exactly that sliding the rotating design removes.
