Different screw types have evolved for specific uses, taking advantage of carbon steel's strength, machinability, and low cost. Common carbon steel screw varieties include self-tapping, self-drilling, T17 timber, and resistant head.Self-tapping screws have threads that cut into the material as they are driven in, creating internal threads for securing into materials like plastics, sheet metal, or wood. Self-drilling screws combine drilling and tapping into one operation, fully eliminating any pilot hole requirement. Self-drilling screws provide fast assembly of overlapped metal sheets or other materials up to moderate thicknesses.T17 screws are designed specifically for fastening into wood materials. They have a thinner shank and tapered shape for reducing wood splitting while providing holding power.  T17s are commonly used in woodworking and construction projects.Resistant screws have special head treatments to withstand specific exposure conditions. A range of coatings and surface treatments have been developed to make carbon steel screws rust-resistant for use in outdoor, marine, and other demanding settings.With the proper screw selection for the materials and conditions at hand, carbon steel screws provide an indispensable, cost-effective fastening solution. Carbon Steel Technical DetailsTypesCarbon contentANSIhardness LevelApplicationcharacterlow-carbon steel0.05-0.3%C10104.8Used for general screwsrelatively low tensile strengthC10184.8Used for Carburized screws or Thin screws with M4.0 diameter or lessC10225.8-Medium-carbon steel0.3-0.6%C10458.8-good wear resistance35ACR10.9Used for thin screws with M4.0 diameter or less40ACR10.9Used for M4~M10 diameter screwsHigh-carbon steel0.6-1.0%- -extremely strong yet more brittlehigh wear resistanceUltra-high-carbon steel1.25-2.0%- -can be tempered to great hardnessUsed for special purposesProduct ApplicationCompany ProfileQuality Control Certifications FAQ    /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
