Our round-head square neck screws are available in A2 stainless steel. A2 stainless steel accounts for over 65% of stainless steel applications, and is superior to the main coatings used in bolting. Its resistance to corrosion is assessed by a PREN of 18. The screw's collar prevents it from rotating while the nut is being tightened. These square-neck screws have a square cross-section at the base of the shank under the head, and are used only with a washer and nut. For wood parts, the square collar makes its imprint in the wood. For metal parts, lights fitted to the square collar. The head has no imprint, so tightening must be done by the nut. Particularly resistant to chloride-free corrosive environments. No surface clinging, so no risk of injury. Facilitates product flow in the case of a chute, for example. Various applications in humid environments.
