T-Shaped Screw

Large Head T-Shaped Screw

T-shaped quad-screws are a fastener that combines high strength and convenient installation characteristics. The head adopts a T-shaped design and is paired with a four-sided drive structure to provide stronger torque transmission capabilities and prevent slippage.

Aluminum Alloy T-Shaped Screw

The aluminum alloy hexagonal double-ended screws are manufactured from high-strength aluminum alloys (such as 6061-T6/7075). The conical screw design enhances the thread grip force and shock resistance. The hexagonal head structure at both ends facilitates bidirectional installation.

Stainless Steel Shaped Screw

The stainless steel square head stepped bolt is a type of fastener with a square head and a stepped design on the shaft. It is usually made of 304 or 316 stainless steel through cold stamping processing. It has excellent corrosion resistance and high strength, and is suitable for use in harsh environments such as machinery, construction, chemical industry, and ships.
