Compared to domestic products, we can offer small lot sizes and shorter delivery times. 【Made in South Korea】 High-strength bolt F10T: Sizes M16~M24 Torsion type high-strength bolt S10T: Sizes M16~M24 Delivery time: Usually 1 month (depending on quantity) Material manufacturers: JFE Steel, POSCO, HYUNDAI Lot size: Starting from 100 pieces 【Made in Taiwan】 High-strength bolt F10T: Sizes M16~M24 Torsion type high-strength bolt S10T: Sizes M16~M24 Delivery time: 6 months (3 months for M22) Material manufacturers: Nippon Steel, CSC, POSCO Lot size: Starting from 1000 pieces For detailed delivery times and prices, please contact us. *For more information, please download the PDF or feel free to contact us.
By using hex bolts that cost less than 1/10 of the material price, it is possible to reduce costs!
We would like to introduce examples of our stainless steel tank and filter housing manufacturing. By designing the fastening parts of stainless steel pressure vessels and tank lids with standard hex nuts instead of eye nuts, it is possible to achieve cost reduction. Additionally, since hex nuts can be used with tools like monkey wrenches, work efficiency is generally improved. For suspension, using only the necessary eye bolts can also lead to cost savings. 【Key Points of the Example】 - Eye nuts are a commonly used fastening method for stainless steel pressure vessels and tanks due to their versatility with specified tools and during suspension, but the components are expensive, leading to increased costs. - By minimizing the use of eye nuts and using hex bolts, which are priced at less than one-tenth of the cost, it is possible to reduce expenses. *For more details, please refer to the PDF document or feel free to contact us.
Can be processed in a short time! We perform hex hole processing used for hex wrenches and other tools.
"Hexagonal hole machining" is performed using a special attachment. Since the machining of hexagonal holes is done through cutting processes, the machining time is significantly shorter compared to methods like electrical discharge machining. Please note that since these are hexagonal holes for hex wrenches, they are not suitable for cases that require very high precision. 【Features】 - Uses a special attachment - Very short machining time - Machining of hexagonal holes through cutting processes
