"Several of the heads are not formed properly and have to be discarded. This is not conclusive to fine work. Painin the the neck picking one up to use and having to throw it in the scrap bin. The 19mm pins I had were the same so must be a problem with the manufacturing process. Approx 1% are defective. It would be nice if screwfix passed this info on to their supplier for rectification."
"As stated by other reviewers these pins are poor quality, but what do you expect for the price. I needed some pins to hold the hardboard on the back of some picture frames, for this they were adequate. You'll reject a lot though, I used about 60 and had at least a 20% reject rate, mainly due to pins with heads at each end or no head at all! About 40% of the ones used had deformed heads. Overall they are ok for rough work but not a lot else.
As you can see I've only given 1 star for Features, Performance and Reliability. What more can I say, only that the review insisted I fill in these fields for a veener pin!!
