Original head shape; anti-tamper screw 'LH Sticks'
The original head shape prevents tampering and helps with "vandalism prevention"! Improved torque transmission increases work efficiency!
The LH Sticks are designed as a fastening system, featuring a unique head shape that can only be used with specialized tools. This head shape allows for stable fastening while enabling weight reduction and a lower profile. Its distinctive shape serves as a theft prevention design, functioning effectively as tamper-proof and security screws. Eliminating the unstable factors in fastening desired for the automation of production lines, LH Sticks achieve minimal play and stable fastening. With LH Sticks, further weight reduction and miniaturization in product design and development can be realized. 【Features】 ■ Durable head shape: Designed to prevent cam-out, allowing for secure fastening. ■ 0° drive angle design: The shape ensures that torque is effectively transmitted to the recess, enabling stable fastening. ■ Excellent adhesion with bits and drivers: The screw and tool fit securely together for safe fastening. *For more details, please download the materials or feel free to contact us.
