Product description

Compiled from the existing technical description of this product on this site

The 0.6 mm CM ultra-thin head serrated locking micro screw has a head only 0.6 mm thick with a precision serrated face underneath; friction on the enlarged contact area provides physical locking, so the screw resists vibration without any adhesive dot. Micro-diameter cold forming gives full and consistent threads, which suits micro assemblies with extreme space limits.

Technical Features
0.6mm ultra-thin head reduces assembly heightMechanical locking via serrations under the head: no adhesive dot, no chemical lockingMicro-diameter cold heading for full thread form and consistent dimensionsLightweight head reduces moment of inertia, suitable for high-speed drivingTooth profile and head diameter made to drawing
Applications
Smart wearables and smartphone mid-framesMicro camera modulesPrecision sensorsMicro motors and micro gearboxes

FAQ

Material, standards, surface treatment and installation points for this model; the data comes from the specification table on this page and from the national standards cited in the answers.

Q1What material is the 0.6mm CM ultra-thin head serrated-face anti-loosening micro screw available in, and what strength level does it reach?

Marked in the specification table on this page: material is high-strength alloy steel. Material certificates and mechanical property test reports can be supplied with the goods; batch acceptance follows the data above.

Q2Which surface treatments are available for the 0.6mm CM ultra-thin head serrated-face anti-loosening micro screw, and how to choose?

Surface treatment marked in the specification table on this page: black oxide / zinc plated (optional). Each coating differs in appearance, corrosion resistance and cost; choose according to the service environment and order agreement.

Q3Where is the 0.6mm CM ultra-thin head serrated-face anti-loosening micro screw used?

Typical applications listed in the product description on this page: smart wearables and smartphone frames; micro camera modules; precision sensors; micro motors and micro gearboxes. Overview: the 0.6 mm CM ultra-thin head serrated locking micro screw has a head only 0.6 mm thick with a precision serrated face underneath; friction on the enlarged contact area provides physical locking, so the screw resists vibration without any adhesive dot.

Q4What are the specifications and dimensions of the 0.6mm CM ultra-thin head serrated-face anti-loosening micro screw?

Specification table on this page: head thickness 0.6 mm. External dimensions and tolerances follow the customer drawing / company standard; a dimensional inspection report can be supplied with the shipment.

Q5What is the locking principle of pre-applied adhesive parts such as the 0.6mm CM ultra-thin head serrated-face anti-loosening micro screw?

A viscoelastic adhesive layer is pre-applied to the threaded section. After the screw is driven in, the adhesive fills the gaps between the thread flanks and gives the thread pair continuous damping and adhesion, suppressing back-rotation. Residual locking capacity remains after re-assembly, but it decreases with the number of assembly cycles. The pre-application process follows the company standard; the thread is GB/T 196, GB/T 197 6g. (Applies to this model: “0.6 mm CM ultra-thin head serrated locking micro screw”.)
