Product range
Fourteen product families covering the fastening, locating and spacing needs of miniature assemblies — made on one site in Bekasi, Indonesia, with the process chain behind them.
01 · Product family
Threaded fasteners from M0.6 to M2, with or without a pre-applied locking element.
4 products
Micro Screws · M0.6 – M2
Micro machine screws that engage a pre-formed thread — a tapped hole, a brass insert or a heat-set nut — and hold their clamp load through repeated disassembly.
Micro Screws · M1.0 – M2.0
Self-tapping micro screws remove the tapping operation: the screw forms its own thread in a plain pilot hole in plastic or thin metal, so the housing needs no insert.
Micro Screws · M1.0 – M2.0
Physical vapour deposition puts a dense ceramic film on the screw in a vacuum chamber — hard enough to resist driver wear, thin enough that it does not close the thread or change the fit.
Micro Screws · From M0.8 × 1.0 mm
Screws supplied with a locking, sealing or vibration-damping element already applied — micro-encapsulated adhesive, nylon patch, sealant or damping coating, from M0.8 upward.
02 · Product family
Ground pins, standoffs, inserts and captive assemblies that locate and space as well as clamp.
0 products
03 · Product family
Stamped parts and security drives for assemblies that need more than a standard fastener.

Geometry reference
The head sets the stack height and the bearing area; the drive sets the torque you can transmit and the cam-out risk on the line. Both should be chosen together.
Rounded top with a flat bearing face. The default for general assembly because it gives the largest bearing area under the head.
Seats flush in a 90° or 120° countersink. Requires a matching countersink in the mating part; the head carries load on a conical face.
Length is measured from the bearing face, not the point, for flat and pan heads. For countersunk screws it is measured over the complete head.
Self-centring and cheap, with deliberate cam-out at high torque. Still the most common drive in consumer electronics below M2.
Six-lobe geometry transmits more torque with less cam-out. Preferred for high-cycle automated lines and for security variants.
The only practical drive below M0.6, where a cross recess cannot be formed reliably. Low torque transfer, but simple and tool-tolerant.
Materials
Strength, corrosion and weight trade against each other. The right answer depends on the mating part, the cleaning chemistry and the service life — not on a preference for stainless.
| Grade | Corrosion | Strength | Weight | Typical finish | Best for |
|---|---|---|---|---|---|
| SWRCH10A | Poor without coating | Low | Medium | Zinc, zinc-nickel | High-volume small parts, easiest to form |
| SWRCH18A | Poor without coating | Medium | Medium | Zinc, zinc-nickel | General micro screws, heat treated where needed |
| SWRCH22A | Poor without coating | Medium-high | Medium | Zinc, zinc-nickel | Parts that need strength after quench and temper |
| SUS302HQ | Good | Medium | Medium | Passivation | Cold-formed stainless, the grade for a clean head |
| SUS304 | Good in normal atmospheres | Medium | Medium | Passivation, PVD | General electronics and housings |
| SUS316 | Best against chlorides | Medium | Medium | Passivation, PVD | Coastal, medical, chemical exposure |
| SUS410 | Moderate | High when hardened | Medium | Passivation, PVD | Self-tapping screws, wear parts |
| TA2 (titanium) | Excellent | Medium | Lightest | Passivation, anodise | Weight-critical, non-magnetic joints |
These are the grades documented in the catalogue. Corrosion ratings assume the stated finish — stainless in a chloride environment can still pit, and bare carbon steel rusts within days.
Finishes
Finish is a specification, not a colour. It sets corrosion life, friction coefficient and appearance — and it changes thread dimensions.
| Finish | Thickness | Salt spray | Friction (µ) | Appearance | Notes |
|---|---|---|---|---|---|
| Zinc trivalent | 5 – 12 µm | 96 – 240 h | 0.18 – 0.25 | Blue / clear | Economic default for steel |
| Zinc-nickel | 8 – 15 µm | 480 – 720 h | 0.15 – 0.20 | Silver / black | Automotive and outdoor |
| Electroless nickel | 3 – 8 µm | 240 – 480 h | 0.18 – 0.22 | Bright silver | Uniform on complex geometry |
| Black oxide | 1 – 2 µm | 24 – 72 h (oiled) | 0.20 – 0.28 | Black | Cosmetic internal parts |
| Dacromet / Geomet | 8 – 12 µm | 720 – 1,000 h | 0.14 – 0.18 | Grey-silver | Highest corrosion, no hydrogen risk |
| TiN PVD | 2 – 4 µm | 96 – 240 h* | 0.20 | Gold | Wear resistance, decorative |
| CrN PVD | 2 – 5 µm | 96 – 480 h* | 0.22 | Silver-grey | Corrosion plus wear |
| DLC | 2 – 3 µm | 96 – 240 h* | 0.10 | Near-black | Low friction, black cosmetic |
* PVD salt spray figures assume an interlayer. PVD alone is a wear and appearance coating, not a sacrificial corrosion barrier. Values describe each system in general; the figure committed to a drawing is the one measured on the part.
Size reference
Thread data for the documented catalogue range. Fine pitch and left-hand threads are a tooling question rather than a catalogue question — send the drawing.
| Size | Coarse pitch (mm) | Tapping drill (mm) | Close fit hole (mm) |
|---|---|---|---|
| M0.6 | 0.15 | 0.45 | 0.55 |
| M0.8 | 0.20 | 0.65 | 0.75 |
| M1.0 | 0.25 | 0.75 | 0.85 |
| M1.2 | 0.25 | 0.95 | 1.05 |
| M1.4 | 0.30 | 1.10 | 1.20 |
| M1.6 | 0.35 | 1.25 | 1.35 |
| M2.0 | 0.40 | 1.60 | 1.70 |
Tapping drill values are practical starting points targeting roughly 75% engagement in steel. Aluminium usually takes a slightly smaller drill, and plastics are specified by body diameter rather than thread. Full thread data sits in the thread standards reference.
Not sure which family?
Three questions usually narrow the choice to one or two families.
01
Metal thread means a machine screw. Plastic means a thread-forming screw, or a machine screw with an insert if the joint will be opened more than a few times.
02
If it acts as a pivot or aligns two parts, you need a ground shoulder screw or a dowel pin — a standard screw with a loose clearance hole will not hold position.
03
Serviceable joints need a nylon patch or a captive design. Permanent joints can use encapsulated adhesive, which holds better but cannot be re-used.
Direct support
We will tell you which family fits, which tolerance is driving cost, and whether a different joint would be cheaper. No obligation, and no sales engineer in between.
Typical reply time
Direct from engineering
Whether you need 10,000 M1.2 screws or a custom stamped contact, the same engineering and quality process applies.
