Precision fastening · Bekasi, Indonesia
We forge, heat treat, coat and inspect precision fasteners from M0.5 to M6 — for electronics assemblies and robotic dexterous hands. One plant, one team, one standard, in Cikarang Utara, Bekasi.
Who we are
Most fastener suppliers are organised around M6 and above, and treat micro screws as a side line. We do the opposite. Our tooling, our inspection equipment and our people are set up for parts you can barely see — because that is where the engineering difficulty actually sits.
Below M2, a burr of 0.02 mm changes how a screw seats. A head that is 0.04 mm too tall breaks a camera module stack. A thread that is 0.01 mm out of round cross-threads in a brass insert. These are not cosmetic details; they are the difference between a line that runs and a line that stops.

Micro screws, precision components and stamped parts — all produced under the same dimensional and documentation controls.
Micro Screws · M0.5 – M6
Precision machine screws from M0.5 to M6 with rolled Class 6g threads, tight head concentricity and clean drive recesses for automated driving.
Micro Screws · M0.8 – M6
Physical vapour deposition coatings that add 2–5 µm of hard ceramic film — for driver wear resistance, low friction and decorative black or gold finishes.
Micro Screws · M0.8 – M6
Screws with a factory-applied locking or sealing element, so the assembly line receives a ready-to-drive fastener with no liquid adhesive and no cure time.
Precision Components · M1 – M4
Male-female and female-female standoffs from M1 to M4, plus plain spacers, in brass, stainless and aluminium — with length tolerances that keep board stacks parallel.
Focus industries
Electronics and robotics are not side markets for us. They set the tolerances, the finishes and the documentation we build to every day.
Sub-M1.6 fasteners for the thinnest consumer devices
Board hardware, chassis fasteners and thermal-stack screws
Fasteners for harmonic drives, cycloidal reducers and frameless motors
IATF 16949 fasteners for ECUs, sensors and battery modules
From wire to carton
A screw that moves between suppliers accumulates tolerance, handling damage and undocumented changes. Ours does not leave the plant.
Incoming wire checked for diameter, ovality, surface and hardness, then linked to a heat number.
Two to four station heading forms the head, shank and point without cutting material.
Threads rolled, not cut, so grain flows along the flank and fatigue strength improves.
Carburising or quench and temper with recorded atmosphere and hardness per load.
Zinc, zinc-nickel, nickel, passivation or PVD, with thickness checked at the thread root.
Nylon patch or encapsulated adhesive applied at a controlled thread position.
Vision and laser inspection at up to 2,000 pcs/min, with reject reconciliation.
Reel, tray, bulk or cleanroom bag, labelled with a lot code linked to production records.
Engineering support
A drawing tells us the geometry. It does not tell us the clamp load, the service cycles or the resin grade — and those are usually where the problem is. Send the assembly context and we will come back with a manufacturability review, not just a price.
01
We check where the fastener sits in the stack and whether the callouts are achievable at a sensible cost.
02
Target preload, friction coefficient and strip torque computed for your actual mating material.
03
Corrosion, friction, conductivity and cosmetic requirements translated into a named process.
04
Samples in one to three days from existing tooling, with a dimensional report.
Board hardware review · M2 to M3 stack Quality system
Certification is the baseline. What matters day to day is that a lot can be traced to a wire heat number and that the inspection record travels with it.

Case studies
Three programmes where the joint — not the gearbox, not the housing — was the limiting factor.
Robotics & Dexterous Hands
A 16-DOF dexterous hand was losing repeatability after 200,000 cycles. Ground shoulder pins and encapsulated screws took backlash out of the finger chain.
Smartphones & Wearables
A camera module stack had 0.4 mm of vertical budget for four screws. Wafer-head M1.0 screws with ±0.02 mm head height made the stack fit without a housing redesign.
PCB, Server & Data Center
An accelerator card was throttling after thermal cycling because heatsink screws were relaxing. Class 12.9 screws with controlled friction held preload through 1,000 cycles.

Practical writing on torque, coatings, joint design and the things that go wrong at micro scale.

At M1 the difference between a joint that holds and one that strips is often 0.04 N·m. Here is how to calculate the window, measure it, and keep the line inside it.

They solve different problems. PVD gives hardness and colour without plating chemistry; electroplating gives sacrificial corrosion protection. Choosing the wrong one is expensive.

Finger joints fail at the fastener long before they fail at the gearbox. Six rules that robotics teams learn the hard way, and how to design around them.

The decision usually comes down to service cycles, wall thickness and annual volume. A simple decision framework for plastic housings.
