DIN 7996 Cross Recessed Pan Head Wood Screws
DIN 7996 cross recessed pan head wood screws, No. 2 to No. 8: shank and head geometry, type H/Zi recess depths and the commercial length ladder to 80 mm.
Last updated: 2026-11
Specifications
DIN 7996 is the pan head wood screw with cross recess — the domed bearing head for timber joints where the screw stands proud deliberately (bracket fixings, hinge plates over pre-drilled holes, board-to-frame work where the head bears on a metal or hard part rather than sinking into wood). The collected tables run sizes 2 to 8 with shank ds max=nom (2016 edition) / ds min, head diameter dk nom, head height k nom and the cross recess data — recess number plus the approximate m depths for type H (Phillips) and type Zi (Pozi) drivers (≈m type Zi 2.4 at size 2.5 to 6.2 at size 8) — and the commercial length ladder 10 to 80 mm with its mass table. As with DIN 7995, the source prints the superseded 12/2010 edition as a separate table (whose first row carries ds min only) and both are transcribed verbatim.
| Standard / scope | DIN 7996 cross recessed pan head wood screws — sizes 2 to 8, edition 12/2016 (supersedes 12/2010; the superseded edition is transcribed as a separate table) |
|---|---|
| Shank / head | ds max=nom and ds min per size (2010 edition prints ds min only); pan head dk nom; head height k nom |
| Cross recess | Recess number per size; approximate m depths for type H and type Zi drivers (Zi ≈2.4 at size 2.5 → ≈6.2 at size 8) |
| Commercial lengths l | Ladder 10 to 80 mm; approximate mass per 1000 pcs (ρ=7,85 kg/dm³) tabulated per size/length |
| Not tabulated | Point type, material, finish — per RFQ |
Materials
- Same wood-screw materials discipline: zinc-plated steel for interior, A2/A4 stainless or coated for exterior, brass for decorative work. Pan head means the head clamps onto whatever is under it — state if that is metal (washer-face requirements) or timber, since head bearing is the joint element here; and confirm H (Phillips) vs Zi (Pozi) tooling from the m columns before volume orders
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 7996 Cross Recessed Pan Head Wood Screws) 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
When does a wood screw need a pan head instead of countersunk?
When the load path wants the head on top of the joint, not inside it: a pan head bears its full dk circle on the surface (or on a bracket/hinge under it), clamps without a countersinking operation, and keeps full head section in soft timber where a csk rim would tear out. It is also the serviceable choice — pan heads take more driver slip-outs before the recess fails, and they can be removed and re-driven without enlarging a csk. Use countersunk when the surface must be flush or the head is in the wear path; use DIN 7996 when you can accept the dome and want the simpler, stronger-on-the-surface joint.
What do the type H and type Zi columns mean?
They are the two cross-recess driver systems the standard prints depth data for: type H is the Phillips geometry, type Zi the Pozidriv — the m columns give the approximate recess depth per driver type per size (e.g. ≈2.9 vs 2.4 at size 3). The recess is cut to accept both, but they are not interchangeable tools: a Phillips driver rocks in a Zi recess and cambs out under torque, a Pozi driver in an H recess seats too deep and destroys it. Production should pick one system and tool the line for it — the registered recess depths let you match driver rails to screw size; tell us which system your line runs and volume is supplied inspected to that recess.
