Product Detail

Shanghai Mac Corporation is a leading Precision Micro Screw manufacturer and supplier.

Precision micro screws are miniature fastening hardware for compact component assembly. Widely used in consumer electronics, precision optical instruments, non‑implant medical devices and micro‑mechanical modules. They solve fastening challenges for tiny thin‑wall components, preventing thread stripping, part crushing and loosening caused by slight vibration in high‑density miniature assemblies.

It consists of drive head, precision‑rolled thread shank and tapered tip section. The drive head transfers torque from matched screwdriver tools; rolled‑thread profile delivers uniform clamping force onto fragile thin‑wall substrates, while tapered tip reduces stress concentration during initial penetration. Different surface finishing layers adjust surface friction coefficient and surface anti‑oxidation performance. Thread tooth contour tolerances are graded to differentiate continuous high‑speed automated assembly and intermittent manual fitting scenarios. Tip‑end geometry is optimized to lower cracking risk on brittle plastic and thin foil‑like components.

1. Stable Thread Fit Precision rolled threads, anti-slip, low assembly defect rate.

2. Tight Tolerance Consistent dimensions, fully interchangeable for auto assembly.

3. Multiple Materials Carbon steel / stainless steel / titanium for varied needs.

4. Diversified Head‑form Design K‑type, P‑type and C‑type heads adapt to different screwdriver bits and limited installation space, no modification required for existing production tooling.

5. Superior Surface Quality Burr‑free smooth surface avoids scratching delicate circuit boards, plastic and thin‑wall metal components during installation.

1. Consumer Electronic Devices For mobile accessories & small internal electronic modules. Compact for tight spaces; stainless steel recommended.

2. Precision Measuring & Optical Instruments For optical devices and micro sensors. Low deformation to maintain accuracy; titanium / stainless steel recommended.

3. Micro-mechanical Automation Equipment For micro transmission & small automation parts. Stable clamping against minor vibration; carbon steel / stainless steel recommended.

4. Non-implant Medical Devices For small auxiliary medical components. Material avoids chemical reaction; medical-grade stainless steel suggested.

Packaging of Precision Micro Screw:

Standard Packaging

Each batch of precision micro screws is sealed in anti‑static inner plastic bags to prevent scratch and contamination. Bags are packed into individual export cartons. Cartons are strapped onto fumigated wooden pallets and covered with waterproof PE film for ocean transit.

Shipping

We support FCL sea freight and LCL sea freight according to total order volume. Air freight and international courier are available for small‑batch spare‑part orders. Available trade terms include EXW, FOB, CIF. Other terms may be available upon request. Shipping costs are calculated based on cargo gross weight, volume, destination and selected transport method.

Lead Time

Samples: 7‑12 working days

Standard orders: 15‑25 working days

Customized orders: 25‑35 working days

Q1: What parameters do you need for quotation of precision micro screws?

A: Please provide thread size, screw length, head type, material, applicable standard, order quantity, destination port and preferred trade terms. Please also provide special requirements for surface finish, tolerance or custom drawings for accurate quotation.

Q2: What is the MOQ and production lead time?

A: Small trial orders are acceptable for standard specifications; custom non‑standard products require certain minimum batch quantity. Standard orders take 15‑25 working days; customized items take 25‑35 working days.

Q3: What inspection documents can you supply?

A: We carry out dimension inspection, thread inspection and surface appearance test. Material test certificates can be provided upon request.

Q4: How do I select suitable material for my working condition?

A: Carbon steel applies to ordinary indoor non‑corrosive scenarios; stainless steel fits damp or weak‑corrosion environments; titanium is selected for lightweight and high anti‑corrosion requirements.

Q5: Can you produce custom‑made micro screws?

A: Yes, we can provide customized head shape, special thread and surface treatment according to customer drawings.
