The definitive version of thin plate sems!!! Can be fastened to any thin plate!
The Full Lock Screw is a washer-integrated screw designed for fastening ultra-thin plates. Typical washer-integrated screws have an incomplete threaded section of about 2 pitches, which prevents thin plates from being securely tightened. However, the Full Lock Screw has no incomplete threaded section, allowing it to securely tighten even the thinnest materials. It is compatible with sizes from M2.5 to M6. 【Features】 - The screw's shaft diameter is smaller than the inner diameter of the nut, allowing for fastening to thin plates without contacting the nut. - It can be completely fastened even to products without fastening elements, such as terminal blocks. For more details, please contact us or download the catalog.
Achieve cost reduction without lowering fastening strength! Easy-to-insert tapping screws for lightweight alloys.
"Altrax" is a tapping screw for lightweight alloys made of aluminum, magnesium, zinc, or die-cast products. It has a high fastening force (axial force), achieving a fastening strength equivalent to or greater than that of bolts (small screws). Additionally, the contact area between the screw threads and the mating material is large, resulting in minimal reduction in fastening force due to environmental changes. The pitch is the same as that of metric screws, allowing for the use of small screws and bolts after forming internal threads with this product. 【Features】 ■ Thread shape - Thread angle 33°: Compared to a 60° thread angle, it has a smaller volume for forming internal threads and lower screwing torque. - Special tip shape: Easy to screw in (close to a triangular shape). ■ Reduction of processes shortens lead time. ■ Cost reduction. *For more details, please refer to the PDF document or feel free to contact us.
