JLHY's self tapping screws with Phillips pan heads are versatile fasteners designed for fastening sheet metal, plastic components, electrical enclosures, and light structural elements. The pan head provides a low, rounded bearing surface ideal for applications requiring a smooth exterior or where the fastener must not protrude. The zinc coating delivers good indoor corrosion resistance at an economical price point.

The Type AB thread form on these screws is optimized for thin sheet materials, cutting clean threads without cracking or deforming the substrate. The gimlet point starts quickly without predrilling in most materials. The Phillips drive design reduces cam-out at high drive speeds, improving efficiency in powered assembly operations.

JLHY's self tapping screws are case-hardened for the right combination of surface hardness (for thread-cutting ability) and core toughness (to avoid brittle fracture). We produce these screws in a full range from M3 to M8 diameter and lengths from 8mm to 100mm. Standard material is zinc-plated carbon steel, with stainless steel variants available for more demanding environments.

These screws are widely used in electrical enclosure manufacturing, appliance assembly, automotive interior trim, HVAC ductwork, and general sheet metal fabrication. Contact JLHY for specifications, custom head configurations, and OEM pricing.
