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.
