Hexagonal Washer drill tail is a special type of screw. The shape of the screw head is hexagonal. This shape is convenient for tightening or loosening operations with tools such as a hex wrench, can provide a large torque transmission, and is less likely to slip. Huasi stated that the screw has a structure similar to a washer, usually located beneath the screw head, which can increase the contact area between the screw and the surface of the connected part, disperse the pressure, prevent the surface of the connected part from being damaged when the screw is tightened, and also play a certain sealing role. The tail of the screw is in the shape of a drill bit. This design enables the screw to be directly drilled into materials such as metal and wood during installation without the need for predrilling, thereby enhancing installation efficiency.

Product Description
    Stainless steel 310S is an austenitic heat resistant alloy with excellent resistance to oxidation under mildly cyclic conditionsthrough 2000°F. Grade 310S is a lower carbon version, less prone to embrittlement and sensitisation in service. The highchromium and medium nickel content make these steels capable for applications in reducing sulphur atmospheres containing H2S.They are widely used in moderately carburising atmospheres, as encountered in petrochemical environments. For more severe carburising atmospheres other heat resisting alloys should be selected. Grade 310 is not recommended for frequent liquid quenching as it suffers from thermal shock. The grade is often used in cryogenic applications, due to its toughness and low magnetic permeability.

This design enables the screw to be directly drilled into materials such as metal and wood during installation without the need for predrilling, thereby enhancing installation efficiency. It is particularly suitable for situations where onsite quick installation is required and predrilling is not convenient. Hexagonal Waser drill tail screws combine the operational convenience of hexagonal heads, the washer function of Washi, and the selfdrilling feature of drill tails. They are widely used in fields such as construction, mechanical manufacturing, automotive manufacturing, and furniture manufacturing.
