0.8mm CD Texture Ultra-Thin Head Micro Screws

0.8 mm CD-texture ultra-thin head micro screw: a slightly thicker head than the 0.6 mm type, for visible faces that need a deeper recess.

Product overviewOverview

These parts are cold-headed and thread-rolled. Going from 0.6 to 0.8 mm buys recess depth, which is what limits driving torque on heads this thin. The CD texture is formed before coating, so the ring highlight survives PVD and no polishing step is added after plating.

installed by electric or hand driver.

Key featuresFeatures

Extra 0.2 mm of head thickness is spent on recess depth.
Generous fillet between head and shank reduces cracking when torque is applied to a thin head.
Drive options include cross, Torx-style star and hex; the star recess resists cam-out better on thin heads.
C1018 carbon steel (carburised) or 304 stainless; nickel and zinc-nickel plating available for carbon steel.

Typical applicationsApplications

TWS charging cases and smartwatch housings
Notebook hinge covers and keyboard brackets
Camera modules and vibration motors

Selection notesSelection

Use the 0.6 mm type where total height is critical, and this 0.8 mm type where the driver needs a deeper recess; the two are not interchangeable in a pre-set pocket.

Frequently asked questionsFAQ

What does the extra head thickness change?

It allows a deeper recess, so the driver engages more and the material under the recess can carry more torque. Where the pocket height is fixed, that extra 0.2 mm has to be found elsewhere in the stack.

What matters during installation of the 0.8mm CD Texture Ultra-Thin Head Micro Screws?

Drive it with an electric or hand screwdriver. Extra 0.2 mm of head thickness is spent on recess depth.

Manufacturing and inspection

Driving torque and head-break torque are recorded before shipment so the assembly line can set its torque window from data rather than trial and error.Alternative materials and finishes can be quoted side by side during sampling, so cost and corrosion resistance can be traded off explicitly.
