I got these with a specific purpose in mind, but I am still in the beginning stages of my project so I've not yet had the chance to use these. However, they're quite solidly constructed and fairly well made. I do wish the handles were more matte for gripping purposes, but otherwise I think these will work great!

These are good clamp knobs. The threads are sharp and well machined. The plastic knobs are attached well and should provide years of use.

These have the standard ultra hard plastic type heads, that can sometime be a bit brittle, but so far so good, and they are very well moulded with no sharp edges, and a glossy finish, though that can be harder to grip than a matte finish and the head and knobs on it are fairly small even for just M6 so can be harder to get super tight (and using a tool would crack the plastic).For £8.50 (Dec '24) for just 4, I dont think the value is great either, they seem overpriced, but the thread is full length, and the head solid on the thread and well made.
