SCREWKING
Wei Shiun Fasteners
ScrewKing is a brand of WEI SHIUN FASTENERS CO., LTD. — 維勳螺絲股份有限公司 — a precision screw manufacturer founded in 1994 in Shulin District, New Taipei City. Forming, inspection, packing and dispatch happen on our own floor, across plants totalling roughly 1,000 ping (about 3,300 m²).
What we are
A manufacturer, and also a supplier of Taiwanese-made parts we do not produce ourselves. Both, and it is worth saying plainly rather than picking whichever answer suits the enquiry — buyers ask because it changes who is accountable when something is wrong. For anything in our own range, that is us.
The work sits below where most fastener plants start. M6 and up is a different set of machines: wire, dies, thread rolling and inspection all change as you go smaller. We are not the only factory in Taiwan working this small, and we would rather say so than pretend to a scarcity that a buyer can disprove in one search. What we can offer is a clear answer on what we will take on, at what quantity, and on what terms. Capabilities, including the limits →

Process
Seven operations, in order:
| # | Operation | What it decides |
|---|---|---|
| 1 | Wire inspection | Everything downstream. Material and surface condition on arrival |
| 2 | Heading | Head geometry, and where cracks and folds appear if the upset ratio is pushed |
| 3 | Thread rolling | Thread form; the blank is smaller than the finished major diameter because material is displaced outward |
| 4 | In-process inspection | Catching a die before it makes a batch, not after |
| 5 | Heat treatment | Hardness — and the point at which decarburisation has to be controlled |
| 6 | Surface finish | Corrosion resistance, thread fit, and hydrogen embrittlement risk on high-strength parts |
| 7 | Final inspection | What ships |
Steps 5 and 6 are where the size range makes itself felt. Several standards stop above it →
Elected by the trade
Wu Jie-wen, general manager of Wei Shiun Fasteners, served as the ninth chairman of the ROC Screw Development Promotion Association, elected in 2011. The association was then 22 years old with over 150 member companies.
It is here because it is the one credential on this site that did not come from us: named, dated, reported by a business newspaper, and decided by competitors. Commercial Times, 26 December 2011 →
The same report notes he started the business in 1987 doing subcontract screw work, which matches the factory registration of 1986 — and explains the account of a father who made one kind of screw for a working life. Subcontracting is making the same screw, repeatedly, for someone else.
We are not going to call this authority. What a chairmanship elected by the trade is worth is a judgement for the reader, and grading our own credential would only weaken it. The source is linked.
Markets
North America, Europe and the Nordics, Japan, and Taiwan. Each asks for a different set of paperwork, and the paperwork is usually what holds a first order up rather than the parts. What each market asks for →
