DIN 1624 Tee Nuts with Prongs
DIN 1624 tee nuts with prongs, M4 to M10 — the flat-flange T nut pressed into wood and soft sheet, its prongs biting the blind hole — with the collected per-size tables: pitch, barrel d e, height H, flange d c and flange thickness c.

Specifications
A tee nut is how you put a machine thread into wood, plywood and soft plastic sheet without a metal insert: the cylindrical barrel carries the internal thread, the flat flange sits on the surface, and the prongs under the flange are driven into the material as the nut is pressed or hammered home — the withdrawal load then pulls the prongs sideways into the fibres instead of pulling the nut out. The collected tables cover M4 to M10 with pitch P, barrel diameter d e, overall height H, flange diameter d c and the flange dimension c. The source repeats thread sizes across variants — M4 appears twice with different heights (6.95/8.95), M6 and M8 each appear in both tables with a standard and a taller column — all reproduced verbatim and labelled, so pick the column matching the required height. Sheet thickness range, prong count/length and materials are not printed by the collected specification and stay per RFQ.
| Standard | DIN 1624 — tee nuts with prongs (T nuts for wood and soft sheet) |
|---|---|
| Series | M4 – M10 (two source column groups; M4, M6 and M8 each printed in standard and taller variants) |
| Tabulated geometry | Per size: pitch P, barrel d e (5.6–12 mm), height H (6.95–16.75 mm), flange d c (15–25.5 mm), flange dim c (0.95–1.75) |
| Function | Prongs bite the host material so a machine thread survives withdrawal loads in wood or soft sheet |
| Materials | Not tabulated by the collected specification — per RFQ (confirm plate thickness and prong engagement for the host material) |
| Attribute | M4 | M4 (tall) | M5 | M6 |
|---|---|---|---|---|
| P — pitch | 0.7 | 0.7 | 0.8 | 1 |
| d e | 5.6 | 5.6 | 6.5 | 7.7 |
| H | 6.95 | 8.95 | 9.15 | 10.3 |
| d c | 15 | 15 | 17 | 19 |
| c | 0.95 | 0.95 | 1.15 | 1.3 |
| Attribute | M6 (tall) | M8 | M8 (tall) | M10 |
|---|---|---|---|---|
| P — pitch | 1 | 1.25 | 1.25 | 1.5 |
| d e | 7.7 | 10 | 10 | 12 |
| H | 13.3 | 12.75 | 16.75 | 14.5 |

Ordering & documentation
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 1624 Tee Nuts with Prongs) 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 10,000 pieces. Stock items run 3–7 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.
Frequently asked questions
How do I choose between the DIN 1624 variants for the same thread size?
By the height column H and what sits behind the nut. The source prints two heights for M4 (6.95 and 8.95), M6 (10.3 and 13.3) and M8 (12.75 and 16.75): the taller barrel puts more engaged thread in the joint, which is the difference between a screw that strips out of two turns and one that clamps for the life of the assembly — worth it on soft plywood and MDF where every turn counts. But the barrel must clear the back of the panel: check H plus the screw engagement against the panel thickness, because a barrel too long stands proud of the blind hole and rocks the flange. All variants in the collected tables share the same flange d c per thread size, so the surface footprint does not change. State the host material and panel thickness at RFQ so prong engagement and barrel length are confirmed.
What is the MOQ and lead time for this nut type?
The minimum order quantity is 10,000 pieces. Stock items ship in 3–7 days; non-stock items are confirmed at quotation. Common sizes in this nut type are widely stocked; confirm the exact schedule against quantity and size mix at quotation.
