Pan-Head Self-Tapping Screws are multi-purpose industrial fasteners combining broad pan-head bearing surface with sharp self-tapping thread. The pan-head spreads clamping pressure evenly over workpiece surface without countersink holes. Sharp cutting thread generates matching internal thread during installation, removing separate pre-tapping procedures and shortening overall assembly cycle.

Pan-Head Self-Tapping Screws are widely deployed across:
Ordinary machine screws demand pre-tapped holes, adding cost. Small-head fasteners create local pressure points, leaving dents on thin materials.
Built-in self-tapping thread eliminates pre-tapping. Broad pan-head distributes clamping force to avoid surface indent.
We are a professional manufacturer with 30-year experience, owning independent mold-making and heat-treatment workshops.
Pan-head screws have a rounded, slightly raised profile with a flat underside that sits atop the material surface without requiring countersinking, distributing load broadly. Flat-head screws sit flush with the material surface and require a countersunk hole.
Yes, our hardened carbon steel and stainless steel self-tapping screws are designed to tap their own mating threads into pre-drilled pilot holes in sheet metals, plastics, and wood substrates.
SUS304 offers excellent corrosion resistance for standard indoor/outdoor use; SUS316 provides superior chemical and marine-grade corrosion resistance; hardened Carbon Steel provides higher tensile strength and torque resistance at lower costs.
Yes, in addition to standard metric sizes ST2.2 through ST6.3, we provide customized tooling for specialized drive recesses (Torx, Tamper-proof, Hex), non-standard lengths, and custom head markings based on CAD drawings.
Quotations are delivered within 24 hours upon receipt of product drawings or physical samples. In-stock products ship within 3-5 days, while custom production batches typically require 2 to 3 weeks depending on specifications.
