DetailsPrecision Screw Selection Guide
1. By space
Where head height is limited choose ultra-low or short heads; where a flush look is needed choose countersunk.
2. By appearance
For visible areas choose the PVD / CD-texture series, with colour and gloss to order.
3. By structure
Where an internal thread or a two-plate joint is needed, use inner-outer super screws and drop the nut.
4. By torque
For low-torque hand tightening choose Phillips; for higher assembly torque with anti-cam-out choose Torx.
5. Material and finish
Stainless and alloy steel available; PVD colours (black, gold, gunmetal and more) matched to the cosmetic colour card.

Precision Screw FAQ
Q1What is the smallest size you can make?
Micro screws start at M0.8 as standard, and 0.6 mm class ultra-low heads are already in stable production; smaller sizes can be evaluated.
Q2Do ultra-low heads strip easily?
Ultra-low heads are paired with high-torque drives such as Torx, giving a large contact area, so normal assembly does not cam out.
Q3How is PVD different from ordinary plating?
PVD is vacuum ion plating: far higher hardness, wear and corrosion resistance than plating, with an even, stable colour — ideal for cosmetic parts.
Q4What is CD texture?
CD texture is a concentric pattern created by precision turning on the cosmetic face; it looks refined and disguises fine scratches.
Q5What is the advantage of inner-outer super screws?
Male thread on one end and female thread on the other: one screw does the job of two, saving space and process steps.
Q6What is the sampling lead time?
Normally 1 to 2 weeks; special finishes depend on process review. Small-batch fast delivery is supported.
