Very soft bits wear quickly. Very brittle bits may snap under impact drivers.<\/p>\n\n\n\n<p>For high-volume assembly, use industrial-grade bits and replace worn bits before they damage screws.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Coated or Stainless Screws<\/h3>\n\n\n\n<p>Coated screws need careful handling because rough or slipping bits can scratch the finish. For corrosion-sensitive screws, compare <a href=\"https:\/\/xzfastener.com\/zh\/products-category\/various-coated-fasteners\/\">\u5404\u79cd\u6d82\u5c42\u7d27\u56fa\u4ef6<\/a> \u5728\u6700\u7ec8\u6279\u51c6\u4e4b\u524d\u3002<\/p>\n\n\n\n<p>Stainless steel screws may also require controlled installation to reduce galling and thread damage. Buyers can compare <a href=\"https:\/\/xzfastener.com\/zh\/fastener-material\/stainless-steel\/\">\u4e0d\u9508\u94a2\u7d27\u56fa\u4ef6<\/a> \u5f53\u9700\u8981\u8010\u8150\u8680\u65f6\u3002<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">\u8981\u907f\u514d\u7684\u5e38\u89c1\u9519\u8bef<\/h2>\n\n\n\n<p>Do not use one bit type for several similar-looking drives.
