Precision fasteners engineered in Indonesia, serving industries worldwide

From wire coil to finished part,
all under one roof.

Cold heading is our core — but it is only the middle of the story. Tool making, heat treatment, thread rolling, surface engineering and automated inspection happen inside our walls, which is exactly how we keep tolerances tight and lead times short.

Seven steps, zero hand-offs

A single accountable process chain — each step measured, each step traceable to the finished batch.

Tool & die making

In-house tool shop builds and maintains the forming dies that define every geometry.

Cold heading

Single- and multi-station forming up to M27 shapes near-net parts in seconds with continuous grain flow.

Heat treatment

Quenching, tempering and aging unlock strength grades from 8.8 to 14.9-development.

Thread rolling

Post-heat-treatment rolling builds residual compressive stress at the thread root for fatigue life.

Surface finishing

Anodizing, plating, PVD and special coatings set corrosion, friction and appearance.

Assembly & machining

Automatic assembly of multi-part fasteners plus CNC finishing of critical features.

CCD inspection

Optical sorting verifies every dimension and drive on high-volume lines before packing.

Core processes

Processes we control daily

Cold heading & forming

Single- and multi-station cold headers from M0.6 to M27, including flange forming, extruding, trimming and complex near-net-shape parts. One operation replaces minutes of machining.

Heat treatment

Full metallurgical control — solution treatment, quenching, tempering and aging — with hardness verification on every batch. The key process behind our high-strength alloys.

Thread rolling

High-precision thread rolling and knurling after heat treatment strengthens thread roots against fatigue — critical for safety joints.

Surface engineering

Anodizing (60-day salt spray), zinc and zinc-nickel plating, PVD, pre-applied adhesives and sealants, PTFE and dry-film lubricants — friction tuned to your assembly target.

CNC machining & finishing

Precision secondary operations on critical features — threads, seating faces, shoulders — only where cold heading cannot deliver the tolerance.

Automated assembly

Multi-component fasteners — pins, springs, plugs, washers — assembled and pre-loaded automatically, with patented equipment that lifts efficiency up to 35%.

Materials & finishes

A material and a finish for every joint

Selection is driven by the joint: substrate, environment, assembly method and cost target. These are the levers we tune most often.

Materials

  • Carbon & alloy steels — 10B21, SCM435 & more; strength grades 8.8–12.9+
  • Stainless steels — austenitic non-magnetic and martensitic grades
  • Aluminum alloys — ZT68 7xxx ultra-high strength, 6056, 6061
  • Copper alloys & specialty — for conductivity and exotic environments

Special surface treatments

  • X surface treatment — hardened anti-adhesion finish for tool screws
  • Zinc & zinc-nickel — up to 480 h red-rust resistance
  • DLC / PVD / CVD — hard, low-friction, wear-resistant coatings
  • Pre-applied adhesives & sealants — locking and sealing in one step
Engineering services

More than a supplier — a design partner

We measure our value in total cost, not unit price. That is why our engineers work upstream, where 85% of a product's cost is locked in.

Design consulting

Joint design, material and drive selection, simulation support and drawing reviews — target: 30%+ faster design cycles.

Rapid samples

From drawing to prototype in as little as one day when every process is in-house — up to one week for outsourced steps.

Teardown analysis

Joint teardown with your team to rationalize drive types, reduce part numbers and replace multi-part stacks with single smarter fasteners.

Process optimization

CNC-to-cold-heading conversions, parameter tuning and design-for-manufacture that routinely cut unit cost 20–60%.

Proof · Case study

One part, three wins:
stronger, faster, 60% cheaper

An EV battery lifting sleeve was conventionally machined from 6061 bar stock — 20 minutes per part, 60 units a day, and a severed grain structure that risked fatigue fractures under lifting loads.

We re-engineered it as cold heading with minimal secondary machining. Grain flow now runs unbroken through the flange and body, material utilization reached 98%, and cycle time fell to under four minutes.
