Hexagon Socket Screw Key Chart — ISO 2936:2001 Metric, s 0.7 – 36 mm, Standard/Long/Extra-long

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 (Hexagon Socket Screw Key Chart — ISO 2936:2001 Metric, s 0.7 – 36 mm, Standard/Long/Extra-long) 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.

Which key goes with which metric socket screw, and when is the long or extra-long series worth specifying?

Match by socket: an M8 socket head cap screw (DIN 912 / ISO 4762) calls an s = 6 mm socket, so the s 6 key with its 6.00/5.95 mm across-flats limits is the driver — the mapping lives in the screw standard's table, and this chart's job is the key's own dimensions and tolerances. The series question is access and leverage: the standard series suits open and shallow sockets; the long series (an s 5 key grows from 85 to 120 mm) reaches sockets recessed below washers, inside counterbores or behind guards, and the extra-long (165 mm at s 5) goes deeper still or adds reach-over leverage — at the cost of tip flex, which at small sizes can begin to round the socket if the key is allowed to lean under torque. Two disciplines protect the socket: keep the key perpendicular under full torque, and check a heavily used key against the chart's across-flats minimum (4.95 mm at s 5) — below that it is a socket-rounder, not a driver. Note the availability ladder the source prints: long and extra-long exist only from s 1.3 mm up, extra-long stops at s 18 mm, and from s 19 upward only the standard series — so a large assembly that needs reach needs a bit-and-holder arrangement, which is a sourcing question to raise at RFQ.
