Need Precision Machine Screws That Meet Strict Assembly Tolerances for Electronic Enclosures?

Our custom pan head machine screws are manufactured with multi-blow header technology and inspected using 2.5D projectors to ensure dimensional accuracy within microns. Every fastener complies with ISO working instructions and undergoes comprehensive measurement of head diameter, slot depth, and thread parameters. Contact us for custom specifications that meet your exact assembly requirements with guaranteed quality control.

With 45 years of manufacturing expertise, our production process incorporates comprehensive inspection protocols complying with ISO working instructions at every stage. Every custom machine screw is meticulously measured using advanced tools including calipers, protrusion-height gages, micrometers, and 2.5D/2D projectors to verify critical dimensions: head diameter, head height, slot depth, slot width, thread length, major and minor diameters, thread angle, and pitch. GO/NO GO ring gage testing guarantees thread accuracy, while salt spray testing validates corrosion resistance, delivering reliable fastening solutions for OEM manufacturers and specialized industrial applications requiring custom specifications.
