DIN 7516 Cross Recessed Countersunk Head Thread Cutting Screws (Form DE)
Cross recessed countersunk head thread cutting screws per DIN 7516 Form DE — M3 to M8 in the collected table, with cutting flutes from the point and per-size head dimensions for flush seating in a 90° countersink.
Last updated: 2026-11
Specifications
The Form DE thread cutting screw is the cross recessed countersunk member of the thread-cutting family: a 90° conical head that seats flush, a Phillips-style recess that centres a powered driver, and cutting flutes that machine the mating thread from the point upward — cutting rather than forming, for base materials where a thread-forming screw would stall. The collected norm table runs M3 through M8 with head diameter d2 (maximum = nominal and minimum), head height h and the m1/m2 figures printed by the source. At M5 the head measures 9.30 mm across (8.94 mm minimum) at 2.7 mm high; at M8, 15.80 mm across at 4.65 mm high. The flush finish depends on the mating countersink being cut to match — the same seating rule as the DIN 7982 tapping screw — and the hole the flutes cut into should be confirmed against the base material. Its slotted oval-head counterpart is DIN 7513 GE; for joints that sit proud instead of flush, the pan-head Form AE of the same standard covers the drive-side alternative.

Frequently asked questions
DIN 7516 DE or DIN 7513 GE — how do the two thread-cutting head forms differ?
By head form and drive. The Form DE screw is cross recessed and seats flush in a 90° countersink — the powered-driver, flush-finish choice; the Form GE screw is slotted with a raised oval head that sits slightly proud — the hand-service choice that tolerates countersink variation. Both cut their mating thread with flutes from the point, and their collected tables overlap across M3–M8, so the head form, not the thread capability, is the selection decision. Keep the form your drawing prints: the two heads are not interchangeable in the seating.
Why does the table keep the m1/m2 column labels as printed?
The collected source table prints the m1 and m2 columns without a dimension legend, so this page reproduces the values verbatim at every size rather than assigning them a meaning the source does not state. Every other column (head diameter d2 maximum/minimum and head height h) is labelled by the source and is quoted as collected. If your drawing keys a dimension to m1 or m2, confirm the interpretation against the current standard edition at quotation.
What is the MOQ and lead time for these thread cutting screws?
Minimum order quantity is 10,000 pieces per item. Stocked sizes ship in 3–7 days; non-stock diameters, lengths or finishes are quoted with a confirmed schedule. Common sizes in this designation are widely stocked — confirm the exact schedule against quantity and size mix at quotation.
What should an RFQ for thread cutting screws state?
State the standard designation and form letter (for example DIN 7513 GE or DIN 7516 DE), thread size and pitch, length, material and finish, the base-material thickness and hardness the screw must cut into, required certificates such as a mill test report per EN 10204 3.1, and quantity per size — plus destination country.
