One thread holds
the whole machine
together.
PT Toprecision Fastening Indonesia engineers and manufactures precision fasteners and connection components in Cikarang, West Java — backed by a global cold-heading group with more than two decades of expertise.

Precision · M0.5 – M27
Engineered for performance.
Manufactured for Indonesia.
At our plant in the Jababeka industrial estate, Cikarang, we combine global cold-heading technology with local manufacturing agility. From micro screws smaller than a grain of rice to M27 structural bolts, we produce fasteners the world relies on — with the responsiveness ASEAN manufacturers need.
We control the entire chain under one roof: tool & die making, cold heading, heat treatment, thread rolling, surface finishing and automated optical inspection. That integration is how we guarantee precision — batch after batch, year after year.
- Vertical production under one roof — no external process hand-offs
- Fast-track samples — from drawing to prototype in as little as one day
- Engineering support in English, Bahasa Indonesia and Mandarin

Lighter. Stronger. Corrosion-free.
The ZT68 aluminum alloy bolt.
Bolts are the hidden weight in every electric drivetrain. ZT68 is a cold-headed, 7-series high-strength aluminum alloy bolt that matches 6.8-grade steel performance at up to 65% lower weight — and eliminates galvanic corrosion against magnesium and aluminum housings without extra coatings or insulating washers.
- Tensile strength ≥ 615 MPa · yield ≥ 490 MPa
- Stable up to 150 °C — minimal preload loss versus steel
- Anodized surface passes 60-day neutral salt spray
- Compact 1.3–1.5d engagement allows thinner housings
From EV batteries to microelectronics
Wherever reliability, precision and volume meet, our fasteners do the invisible work.
Precision is a process, not a promise
Every order runs through an integrated production and quality system designed to remove variation — from the first tool strike to the final optical inspection.
In-house cold heading
Single- and multi-station forming from M0.6 to M27 with near-net-shape accuracy and up to 98% material yield.
Heat treatment & coatings
Quenching, aging, anodizing and special surface treatments — including X-coat and anti-galling finishes — under control.
Certified quality labs
Metallography, hardness, tensile, salt-spray, friction coefficient and RoHS testing on-site to IATF 16949 standards.
Application engineering
Design consulting, 1-day prototyping, joint teardown analysis and cost engineering across the product lifecycle.
