About YOUNGSAN BOLT
One craft since 1990: hot forged bolts. Here is where we came from and where we are going.
“We tell you clearly what we can make — and what we can’t.”
Since our founding in 1990, YOUNGSAN BOLT has stayed with a single craft: hot forged bolts.
Our production range covers diameters up to 100mm (4") and lengths up to 1,000mm (40"). Forging, machining, heat treatment and inspection are coordinated in-house, and we have manufactured over 1,500 different product specifications.
Our flexible small-lot, multi-product system is certified under ISO 9001, ISO 14001 and KS, and we have worked with around 250 customers in Korea and overseas to date.
We will continue to invest in quality and technology, and to stand beside our customers whenever they need us.
