Q:What is your main products?
A:Fasteners, Bolt, nut, screws, washer, threaded rod, anchors, self tapping screws, self driling screws, stainless steel plate, etc.
Q: What is your delivery time?
A:It depends on if we have stock or not, if we have stock goods, we can delivery within 2 days after receive the payment. And normally our production is in 20-30 days for one container (20-26 ton) products.
-
Material: Case-hardened carbon steel (CHQ 1022A) – core hardness 320-420 HV, surface 0.15 mm carburized for superior thread strength.
-
Finish: Mirror nickel plating 8-12 µm; 48 h neutral salt-spray to white-rust, 96 h to red-rust (ASTM B117).
-
Drive: Cylindrical hex socket (DIN 912/ISO 4762 style) – eliminates cam-out, accepts standard Allen keys or hex bits.
-
Head: Cylindrical pan or countersunk options; head diameter 2×nominal thread for large bearing surface.
-
Thread: Sharp Type-B (sheet-metal) or Type-C (plastic/wood) self-tapping flute; cuts its own mating thread in 0.8–3 mm substrates.
-
Point: 45° cutting gimlet point for fast start, reduced splitting and low drive torque.
-
Temperature Range: –40 °C to +120 °C; nickel layer remains bright up to 150 °C.
-
Reusable: Threads stay intact after 15+ removal cycles in steel or aluminum.
-
Diameter: ST2.9 (4#) – ST6.3 (14#) / M3 – M6
-
Length: 6 mm – 80 mm (1/4" – 3-1/8")
-
Head Styles: Pan head, CSK 90°, wafer head, hex flange (custom)
-
Standard: DIN 7504 / ISO 1487 (self-tapping) + DIN 912 head geometry
-
Drive Size: 1.5 mm – 5 mm hex (matching table on tech sheet)
-
Certifications: RoHS, REACH, SGS salt-spray report provided.
-
Use high-quality hex bit (HRC 58+) for longest life.
-
Pilot hole: 0.8 × root diameter for metal; none needed for softwood.
-
Drive at low-medium speed; nickel finish acts as micro-lubricant—no additional oil required.
-
Avoid power-impact drivers on CSK heads to prevent plating flake.
