Carbon Steel Round Washer Head with TORX PLUS Screw

Name: Alloy Steel Thread-Locking Button TORX Drive Screws

Material: Carbon steel, alloy steel, Stainless steel SUS304, SUS316， A2-70, A4-80, titanium alloy, aluminum alloy.

Made from alloy steel, these screws are nearly twice as strong as stainless steel button head screws. A nylon patch bonded to the threads adds friction to prevent loosening from vibration. Their black-oxide finish provides mild corrosion resistance in dry environments. Length is measured from under the head.

Metric 18-8 Stainless Steel Flanged Button Head Screws: Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. They have a flange that distributes pressure across a wide surface, eliminating the need for a separate washer. All are passivated for added protection against oxidation and corrosion. Head height includes the flange. Length is measured from under the flange.

Metric 316 Stainless Steel Flanged Button Head Screws:316 stainless steel screws resist corrosion from chemicals and saltwater better than 18-8 stainless steel screws. They have a flange that distributes pressure across a wide surface, eliminating the need for a separate washer. All are passivated for added protection against oxidation and corrosion. Screws may be mildly magnetic. Head height includes the flange. Length is measured from under the flange.
