Carbon Steel Self Tapping Screws

↵

Carbon steel hexagon socket tapping screws (carbon steel tapping screws) are fasteners designed for connecting speakers, audio equipment, thin sheet metal and wooden structures. The product is made of 1022 carbon steel and manufactured through an 8.8-grade high-strength cold heading process. The surface is treated with black oxide, which has both rust resistance and industrial aesthetics.

The unique arc-shaped triangular thread section design, combined with a sharp tail end, achieves low screw-in torque and high locking performance. It can be directly installed without pre-drilling in scenes such as 0.5-6 mm-thick color steel plates, wooden speaker panels, and metal brackets.

Core product features

High strength and durability: 8.8-grade hardness standard, the thread surface is strengthened to ensure the connection stability of audio equipment in a vibrating environment, the black surface is treated with anti-rust, the black oxide coating provides corrosion protection, and the salt spray test is greater than 480 hours, which is suitable for use in humid environments.

Precision engineering structure: The integrated design of self-drilling and self-tapping realizes the simultaneous completion from drilling to tapping to the final locking. Shorten the product installation time. The cylindrical head hexagonal design can withstand 200% more torque than cross-slot or slotted screws, and is suitable for high-frequency installation scenarios.
