Product Overview
Optimize your assembly processes with our Steel PT Thread Screws, engineered for precision fastening in plastics, sheet metal, and
composite materials. Designed with self-tapping PT (Type T)
threads, these screws eliminate the need for pre-drilling, reducing
installation time and labor costs. Available in three specialized
variants (WN1412, WN5412, WN5452), they deliver exceptional grip,
vibration resistance, and durability for automotive, electronics,
HVAC, and industrial applications.
Key Features
✅ Self-Tapping PT Thread Design
Sharp, tapered PT threads cut cleanly into plastics and thin metals
(up to 2mm thick), creating secure, stripped-proof threads without
pilot holes.
✅ High-Strength Steel Construction
Crafted from carbon steel (Grade 1018/1022) for superior tensile
strength and fatigue resistance. Optional zinc plating or phosphate
coating enhances corrosion resistance.
✅ Multi-Head Design Options
- WN1412: Pan head with Phillips drive for flush, low-profile
installations.
- WN5412: Wafer head with JIS drive for reduced surface contact and
anti-slip performance.
- WN5452: Hex washer head for high torque applications requiring a wrench
or socket.
✅ Vibration & Loosening Resistance
Thread-locking grooves and precise thread pitch prevent loosening
in dynamic or high-stress environments.
✅ ROHS & REACH Compliance
Free from hazardous substances, ensuring safe use in consumer goods
and industrial equipment.
