BOLTNOTE · INDUSTRIAL FASTENERS · KOREA
Bolts, nuts and studs for your plant in Korea — quoted in English.
Send your BOM or RFQ in English as it is: Excel, PDF, a drawing or a photo. We read every line — standard, size, grade, coating and documents — and source it from suppliers in Korea. Quotations and tax invoices are issued in Korean won (KRW).
Weekdays 09:00–18:00 KST. Up to 20 lines are quoted within 1 business day; for longer lists we tell you the reply date first.
Who this is for
Engineers and buyers at foreign-owned plants, EPC sites and maintenance contractors in Korea who work with English BOMs and ASTM / ASME / ISO / DIN designations, and who need a Korean supplier that reads them line by line.
Metric and inch
Hex bolts and nuts, socket screws, washers, threaded rod, pins and rivets in metric sizes; inch UNC/UNF and 8UN fasteners, including ASTM A193 / A194 / A320 studs with heavy hex nuts for flanged joints.
Read line by line
Each line is checked for standard and edition, size and pitch, length basis, grade, coating and required documents. Missing specifications are collected into one question list instead of being guessed.
Told up front
We hold no stock: every order is sourced from suppliers in Korea. Prices and lead times are written only after the supplier confirms them. Lines we cannot supply are listed with the reason.
How it works
- Send — e-mail the BOM, RFQ, drawing or photo in English. No form to fill in.
- Line check — a mechanical engineer reads every line against the stated standard and grade.
- Questions — open points (length basis, coating, certificates …) come back as one list.
- Quotation — a quotation in KRW with a clarification & deviation sheet and a list of lines that cannot be supplied.
RFQ example
Copy it into your own e-mail and replace the brackets. Your existing format is fine too.
Subject: RFQ – [project / plant name] – [number of lines] lines Company / plant: [name, site in Korea] Contact: [name, e-mail, phone] Delivery to: [city / site in Korea] Needed by: [date] Line | Description | Standard | Size | Grade / material | Finish | Qty 1 | Stud bolt w/ 2 heavy hex nuts | ASME B18.31.2 / B18.2.2 | 3/4"-10UNC x 120 mm | A193 B7 / A194 2H | HDG | 64 sets 2 | [ ] | [ ] | [ ] | [ ] | [ ] | [ ] Documents required: [e.g. EN 10204 3.1 mill certificate, CoC] Special requirements: [NACE, impact test, PMI, marking …] Attachments: [BOM .xlsx / drawing / photo]
Good to know
- Delivery is within Korea. Quotations, orders and Korean tax invoices are in KRW for companies registered in Korea.
- Orders are confirmed by e-mail after the quotation; nothing is ordered automatically from this website.
- Mill certificates and other documents are quoted only when the supplier confirms they can be provided.
- One-person business: the owner, a mechanical engineer with 7 years in rotating equipment, reviews every line personally.
Dimension tables
96 fastener dimension tables (hex bolts and nuts, socket screws, washers, pins, rings …) with the basis of each table stated. Labels are in Korean; sizes and values are in mm or inch as in the standard.
The rest of this website is in Korean. Korean-speaking colleagues can use the Sales inquiry page (Korean) or the product guides (Korean).
