Insert Nuts Type D M6 x 13mm 50 Pack is rated 4.5 out of 5 by 34.
Rated 5 out of 5 by from perfect for garden seat slats I needed to replace the hardwood slats in 3 metal framed chairs, so needed 72 of these. The slats were 17mm english oak and experimentation showed I needed a 9mm hole. I used a 6mm socket and ratchet to screw them in. The thread is angled to screw, not hammer. Using a rachet was easier to apply the driving force rather than use a hex key. The 6mm hex is sloppy but a 1/4" is too big. With a smaller pilot hole (8.5mm) the effort was more and rounded the hex head (but oak is a hard wood!). in softer wood the inserts could end up flush, in oak they stayed very slightly proud, but not an issue for my needs. When the M6 bolts were fitted with a torqued driver all of the inserts stayed tight and didn't pull out. Recommended.

Rated 5 out of 5 by from Insert Nuts Type D M6 x 13mm I tried these a year ago and now I use them all the time when I do prototype pieces. You can also cut a small slot in the top as well. All types of uses in wood, fibreglass and with care metal. Highly recommended. Best use is a self built router table. useful in gypsum walls

Rated 1 out of 5 by from Rubbish Decided to buy these over another brand I use mainly because I was buying a few other bits from screwfix.. I used an 8mm drill bit to drill the hole for the nut as always done with other nuts and as I was tightening it up they split it happened 3 times leaving me struggling to get the nut out.. poor quality in my opinion and I'll be going back to get the other branded nuts that should of done in the first place lesson learned! Quality over quantity

Rated 1 out of 5 by from Poor Quality The metal is very weak, when screwing the inserts into an 8mm predrilled hole the tops ring off quite easily.

Rated 1 out of 5 by from Insert Nuts problem. M6 x 13mm I had to purchase 6 packets to get 2 packets that were OK. The useless ones must have come from a bad batch, as the thread was skewed so the bolt only went in a few millimeters, then stuck. Out of 50 in a pack, between 3-5 were useful. The funny thing was, the ones in the packet that were OK had a better quality (thicker) plastic bag! (coincidence?) The ones that were OK are well worth the money though, just a shame I had to go back (3 times!) to swap (and then replace) the replacement ones back. I have used these before and never had this problem, just hope they have got rid of the badly made ones I returned .

Rated 2 out of 5 by from Fautly thread Thought it would be a great way to assemble wooden posts but most inner threads were faulty (40 out of 50!!). Should have tested before assembling as most of my wood now unusable.

Rated 4 out of 5 by from Handy little fastener Great little fastening product. it finishes nice and flush. I used some in beech and without countersinking they sat nicely flush with the surface of the hardwood. They are neat in appearance when installed and there are plenty in the bag for the price.

Rated 5 out of 5 by from Perfect Bought to repair our bed as the original ones had sheared the retaining fins. Biggest problem was finding them on the Screwfix website as I had no idea what they were called - had seen them on a previous visit so knew they were stocked. Very happy although would rather of had a pack of 10 than 50 :)
