Jhanw Star Knobs M8*35mm Studs

Key specifications

A clamp or fixture that is hard to tighten by hand can slow down a small adjustment. These Jhanw star knobs are designed to give your fingers a shaped grip, so you can turn the fastener directly instead of reaching for a separate tool. The listing describes a Bakelite knob with a threaded metal insert and an M8*35mm stud.

The pack contains four knobs. A nickel-plated finish is also specified for the threaded metal part. The key fit detail is the M8 thread and 35mm stud length: both need to suit the hardware you plan to replace.

Who it’s for

These are aimed at someone replacing a hand-tightened knob on a base, clamp, woodworking fixture, or another listed type of adjustable setup. The star shape gives your hand multiple points to grip, which is useful when you need to loosen or secure a fitting during a workbench adjustment. They’re also listed for speaker stands, automotive adjustments, and VESA mount screws, but that doesn’t establish compatibility with every stand, vehicle part, or mount.

It suits you if you already know the replacement needs an M8*35mm stud and want a hand-operated knob rather than a plain screw head. Not the best choice if your existing hardware uses a different thread or stud length, a matching-looking knob won’t make an incorrect fit work.

What you get

The product is described as a four-pack of black Bakelite star knobs with threaded metal studs. Installation is a screw-on process, and the listing says it does not require special tools. In practice, you could thread one onto a compatible woodworking fixture, tighten it by hand to hold the setup, then loosen it again when repositioning the work. That’s a more direct approach than replacing an entire fixture when only its tightening knob is the part you need to change.

The listing also describes the nickel-plated surface as waterproof and rustproof. Treat that as a stated finish feature, not proof that the entire assembly suits every wet or demanding industrial environment. No load rating or specific compatibility list is provided, so those details can’t be used to judge a particular application.

Before you decide

How many knobs are included? The product name specifies a four-pack.

Does installation require a tool? The described screw-on installation is intended to work without special tools, with the knob tightened by hand.

What should I match before ordering? Compare your hardware’s thread and stud length with the listed M8*35mm specification. The product description does not provide a broader fit chart.

Should you buy it?

Choose this set when the job is a straightforward replacement of compatible hand-tightening knobs and having four on hand is useful. Its appeal is the combination of a shaped grip, Bakelite knob, and threaded metal stud, not a promise that it will fit every clamp or stand named in the listing. If you need a different thread, a different stud length, or confirmed fit for a specific assembly, identify those requirements first, for an exact match, that check matters more than the broad list of possible uses.
