M4 Torx Head Screws



Stainless Passivation Process Introduction

The stainless steel passivation liquid adopts the latest catalytic technology, so the passivation speed of the improved product is faster and the corrosion resistance is stronger than before. Through the passivation of this product, a dense passivation film can be formed at 5-15min, while maintaining the original gloss of the work piece without damage to the work piece size, and the performance of the neutral salt fog can be increased by 10-30 times.

  • 6 X 3/8 Self-Tapping Screws Torx(R) / Pan Head / Type A / Steel / Zinc. A thread forming tapping screw with wider spaced threads than a Type-AB and a gimlet point. For self starting in thin (.015.050 thick) metal or resin-filled plywood. 18-8 Stainless steel tapping screws may be used in.
  • Machine screws are used to secure panels and parts through existing, tapped holes on electronic equipment, engines, and large machines. Fillister and cheese head screws have deep slots to allow increased driving power. Flat head machine screws lie flush with the material surface.

Description:

Flange button socket screws from ITA Fasteners are protective fasteners which provide the assembly with structural support as well as a visually appealing look. It protects the components around it from damages like scraps and unintentional cuts. Another advantage of these screws is the large under head bearing surface - this eliminates the need for washers. It could also be considered as a built-in washer. These screws are fully threaded to provide its users with grip and accurate positioning.

Although these screws have a considerably high load bearing strength, it is not advisable to use them in high strength applications. The stainless steel, carbon steel or alloy steel make gives these screws an additional corrosion resistant property. They are mostly used in applications where the surface area of operation is not sufficient enough for the usage of a wrench. This means that they are often used in machining and assembly processes which do not exert too much torque on its body.
