This comprehensive stainless steel self‑tapping screw series complies with GB, DIN, ISO, and JIS standards. Available with multiple drive options including cross recess, hex socket, and torx. Various head types include pan head, countersunk head, large flange head, washer‑integrated head, external hex head, and flat head. Tail versions cover sharp pointed tail, flat tail, and cutting‑tail self‑tapping screws.
Materials include 304, 316, and 410 stainless steel with full ST self‑tapping thread. No pre‑machined thread is required; the screws can tap threads directly into substrates. 410 grade provides higher hardness for hard sheet materials. Cutting‑tail screws feature chip‑removal slots to prevent workpiece cracking during installation. Stainless steel delivers outstanding rust‑proof and corrosion performance, suitable for both indoor and outdoor harsh environments.
Widely used for electronic housings, furniture, metal sheets, plastic parts, and outdoor equipment. Full‑size range supports large‑volume orders. We supply one‑stop fastener solutions for overseas purchasers, simplifying your sourcing process. Every batch undergoes dimension inspection to guarantee stable quality.
