These have the standard ultra hard old fashioned bakerlight feeling 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 and not hollow undermeath like some others (slight indentations underneath only), The gloss finish can be harder to grip than a matte finish and the head and knobs on it are fairly small for M8 imo so can be harder to get super tight (and using a tool would crack or chip the plastic).For £10 (Dec '24) for 6, the value is just about ok only, they seem a little overpriced, but the thread is full length, and the head solid on the thread and well made and finished, so not too bad if you only need a few.Annoyingly, each one is in a plastic bag, then the whole lot in another plastic bag - totally pointless waste so loose marks for this too.
