Non Standard Flat Thread Rolling Dies High Precision Fastener Mold

This mold is specially customized for STT triangle taper tail self-tapping screws. The unique triangular thread and concentrated sharp taper tail enable strong piercing performance, widely used in furniture wood boards, thin metal sheets, plastic and construction fastener production.

We provide DC53 alloy steel and SKH-9 high-speed steel for options. SKH-9 is the preferred material for mass production of stainless steel STT screws, with higher wear resistance and longer service life. All blanks are high-strength mold steel with Taiwan vacuum hardening treatment.

1. Integrated triangular thread + bundled taper tail design, the screw tip is neat without burrs; 2. Excellent penetration, saving assembly labor for wood and sheet metal; 3. Balanced hardness and toughness, not easy to crack during continuous high-speed rolling; 4. Vacuum nitriding surface treatment greatly reduces abrasion and replacement frequency.
