What it is

The Unifix clamping handwheel with threaded stud (code 0237-930-520-01) is the practical solution for manually adjusting bolts and fastening systems where precision and speed are essential. Designed for professionals in industry, construction and mechanical maintenance, this accessory simplifies tightening operations without using power tools, reducing time and the risk of errors.

A wing knob (or star knob) is a hand knob with a threaded stud or hole, tightened by hand onto a thread.

What it is for

Used for assembling steel structures, in steel fabrication, from cutting to assembly and for mechanical fixing of structures and components to walls, ceilings and floors.

How to use it

Choose the thread of the same size as the stud or hole it is to be fitted to. Screw it on by hand until it sits against the part, then tighten using finger strength only, so it can be removed without tools. Use it where the fixing needs frequent adjustment or removal, not where a firm tightening torque is required.
