DIN 966 Cross Recessed Raised Countersunk Machine Screws
Cross recessed raised countersunk head machine screws per DIN 966 — current norm DIN EN ISO 7047 — M1.6 to M10 in steel class 4.8 or A2/A4 stainless, thread 6g. The oval head with a centred driver: flush seat, crowned finish, production-line drive.
Last updated: 2026-11
Specifications
DIN 966 completes the raised-countersunk pair: the same crowned-over-countersink head as DIN 964, with the cross recess of DIN 965 in place of the slot. The collected standard table runs M1.6 through M10 in steel class 4.8 or A2/A4 stainless, thread tolerance 6g. At M4 the head seats at 7.5 mm maximum diameter (7.14 mm minimum), the raised face rises approximately 1 mm, and a No. 2 cross recess — Type H depth ≈4.5 mm, Type Z 4.6 mm — takes a Phillips driver with full centring; the minimum thread length is 22 mm. DIN 966's current norm is DIN EN ISO 7047. Choose it where the oval-head finish meets powered assembly — enclosure lids, instrument panels, switchgear faceplates — and the slotted version (DIN 964) is the choice where a flat blade remains the service tool.

Frequently asked questions
DIN 966 or DIN 964 — the same oval head, so which one do I order?
Decide by the driver, not the head. The two standards describe the same raised countersunk geometry over overlapping ranges, and the collected tables agree on the M4 figures: 7.5 mm head diameter, roughly 1 mm of raised face. DIN 966's cross recess centrs a Phillips driver and stands up to powered assembly; DIN 964's slot is the serviceable-with-anything choice for instruments and equipment maintained by hand. If your drawings say one, ordering the other invites the wrong driver at the bench — keep the designation and state it on the RFQ.
What is the MOQ and lead time for these machine 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 these machine screws state?
State the standard designation (for example DIN 965, DIN 964, DIN 966 — or the ISO designation your drawing prints, such as ISO 7046, ISO 2010 or ISO 7047), thread size and pitch, length and head dimension, strength class or material (such as 4.8, A2-70, A4-80 or brass), finish (black oxide, zinc plated, or plain), required certificates such as a mill test report per EN 10204 3.1, and quantity per size — plus destination country.
