Perfect fit. I had purchased the same screw but ¾ inch long which was too long so I went with the ½ inch size and it fit perfectly. They are as pictured with a durable finish and well cut threads. I will buy them again if ever needed. I recommend these screws.

Well made and 3/8-16 threads were flawless. Lengths consistent. Worked for me. Note: Socket hex head size is 7/32 on these. They arrive lightly oiled and bagged in box. Less than half price to those peddled by local, surly, know nothing, red vested hardware thieves and as good or better. Without the trip and the lip

High quality. We were looking for a flat headed bolt that was long enough to attach our Trex boards to metal stair stringers. None of them had misthread problems so we were really pleased with the quality. Highly recommend.

Like: Perfect fit for Shopsmith’s MK V 510 Table Saw Insert.Dislike: Finish deteriorates close to the head. Threads are a bit rough and size appears to vary. Since I’m using these on an aluminum casting, the steel threads will alter the aluminum hole, so I will have to chase them first with a die.

I was very surprised to see these SAE size (1/4"-20) with a Metric grade rating, 10.9As you know, 10.9 is roughly equivalent to a Grade 8 in SAE specifications.That means that these screws are not manufactured with Gummi Worms (Chinesium) but rather they are made out of good quality steel. Very nice.Looking at them closely, they are actually very well made and I expect them to last longer than me.
