M16-1,5 x 90 mm Sechskantschrauben | Klasse 10.9 Stahl verzinkt | Vollgewinde (100 / Packung)

The hex head on these bolts fits my socket wrench perfectly, and the 10.9 grade steel feels solid for the heavy machinery repairs I'm doing. No stripped threads or deformation so far after a week of tightening to high torque.

Picked up a pack for a fabrication jig that needed serious holding torque, and the fully threaded 90mm length bit into the steel plate just right. The hex head seated perfectly with a standard socket wrench, no slippage at all. These feel solid enough for years of heavy use.

Used these to bolt down a heavy machine base at the shop, and the class 10.9 steel is seriously tough—no stripping even under high torque. Fully threaded length meant I could adjust the fit without extra washers, and all 100 came out of the bag uniformly coated.
