Parafusos de ombro com soquete M8 x 100 mm | Cabeça de soquete | Acionamento soquete | Aço-liga (50 / emb.)

I needed a long pivot for a jig I was building and these M8 x 100mm screws with the precision-ground shoulder slid right into the bearing surfaces without any wobble. The hex socket drive bit seated firmly, so torquing them down was a breeze. Solid buy for the price.

The precision-ground shoulder really does make these glide smoothly as pivot pins, no binding or chatter when I test-fit them. The 100mm length gives plenty of grip for my jig setup, though I did have to chase a couple of threads with a tap before they’d seat cleanly.

Finally a shoulder screw with enough length and precision for my jig builds — the 100mm reach lets me stack multiple bearings without needing a custom part. The socket drive made installation a breeze even in tight spots.
