Product Description

Round Head Torx Screws ® (Socket Screws)

1. Head Design: An Ingenious Fusion of Round Head and Plum Blossom Groove

Round Head:

• Hemispherical Top: Exhibiting a diameter typically 1.5 to 2 times that of the screw itself, such as a round head diameter of approximately 6-8mm for a 4mm screw diameter, this design artfully disperses stress while safeguarding surfaces from the menace of sharp corners.

Embedded Design: An impressive transition radius of ≥ 0.5mm between head and rod is meticulously crafted to diminish stress concentrations, making it a prime choice for environments rich in vibrations, such as mechanical and sports equipment.

• Plum Blossom Trough (Torx) ® / Star Shaped Slot:

Hexagonal Star-Shaped Groove: Masterful high torque transmission is effortlessly achieved through specialized batch heads, such as the T10-T25 specifications, enhancing anti-slip capabilities by over 60% compared to traditional cross grooves. Ideal for the high-speed installation of electric tools, operating optimally at speeds ≤ 2800RPM.

Anti-Overload Design: Ingenious positioning ribs within the groove flexibly deform under excessive torque, preventing head breakage by ensuring the batch head remains resilient through elastic deformation.

2. Thread and Stem Characteristics

• Thread Type:

Self-Tapping Thread (ST Series): Equipped with a tip featuring 3-4 cutting edges, it effortlessly penetrates thin metal plates up to 2mm thick or plastics without necessitating pre-drilled holes.

Machine Thread (M Series): Optimally paired with nuts or internally threaded holes, this thread is designed for high-load scenarios, such as in steel structures and automotive components.

• Material and Coating:

Carbon Steel (10B21/45# Steel): Post-heat treatment, this material achieves a formidable hardness of HRC35-40, making it ideal for standard indoor loads.

Stainless Steel (304/316): Boasting outstanding corrosion resistance, this material is perfectly suited for outdoor or humid environments, including food machinery and medical equipment.

• Surface Coating:

Galvanized (Blue White/Color Zinc): With a salt spray test endurance ≥ 48 hours, this coating caters to general industrial rust prevention needs.

Nickel-Based Alloy Coating: Demonstrating exceptional durability with salt spray resistance ≥ 1000 hours, this coating is designed for maritime or chemically corrosive settings.
