DIN 2510 L/NF Stud Bolt and Nut Weight Chart

Documents

Shipments are backed by Mill Test Certificate (MTC), Dimensional Report, Salt Spray Test Report on request, with full batch traceability from raw material to finished product. Quality management follows the owner-confirmed compliance list: ISO 9001:2015, RoHS, REACH. Exact document sets are confirmed on the order.

Quotation

• The fastener family (DIN 2510 L/NF Stud Bolt and Nut Weight Chart) plus the standard designation from your drawing — DIN / ISO / JIS / ASTM / ANSI, or a drawing for custom parts.
• Size (diameter and length), thread type (metric or inch), property class or grade, and coating or finish.
• Quantity per size and your target delivery date.
• Destination country, and any required documents (for example a mill test certificate) so the quote includes them.

Sample & supply

Minimum order quantity is 1,000–10,000 pieces depending on size. Stock items run 3–7 days. High-strength and custom parts run 15–25 days. Quantities or variants outside the standard range are confirmed at quotation.

Storage & shipping

Parts are packed for export and shipped factory-direct to buyers in Europe, Asia, the Americas and the Middle East. Store fasteners dry and protected until installation, and keep coated parts in their packaging until use; specific packing and preservation requirements can be stated on the order and confirmed at quotation.

Why are DIN 2510 wafer studs lighter than ordinary studs of the same size — and when does the difference pay?

Because the shank is turned down to roughly the pitch diameter: only the threaded ends carry full diameter. The chart shows the consequence in kg — at M36 x 180 the tabulated 2.045 kg per stud sits well below what a full-diameter stud of the same size and length weighs. That lighter shank is not a cost gimmick: the reduced, smooth section lowers notch exposure along the length and is the classic choice for high-temperature flanges where the stud must flex with thermal cycling. The weight difference pays where it multiplies: a reactor flange requiring dozens of stud-and-nut sets sees the freight and handling difference directly, and the per-nut row (0.425 kg at M36) lets the set be priced complete. Note the chart weights are nominal planning figures from the collected source — certified weights per delivery come with the certificate, per RFQ.

The M24 row shows 78.48 at L210 — is that the real weight?

Almost certainly not, and the page says so. The surrounding ladder at M24 runs 0.5048 (L80) through about 0.9 kg in that length range, so a 78.48 kg single stud is off by two orders of magnitude — the collected chart prints it that way and we carry it verbatim with an anomaly flag rather than silently "correcting" it to a guessed value. The buying discipline this row illustrates applies to any chart weight: treat published per-piece weights as planning numbers, check any figure that sits off its column ladder (this one is flagged in the rendered table), and require the certified weight on the delivery paperwork for anything where freight or criticality makes the kilo matter. For the M24/L210 line specifically, ask on the RFQ and we confirm against the stock item.
