Design: Made of stainless steel,hard and tough (54 HRC) thanks to vacuum ice-hardening. With Hex-Plus geometry. This reduces the notch effect and the destruction of the screw head, at the same time 20% more static torque. The ball head allows for screwing in inclined positions. Delivered in a wear-free solid rubber clip, with abrasion-resistant size identification.
Application:Special product for preventing rust in the processing of stainless steel screws.
