For cylinder connecting sleeve, ISO 4017 is the governing document for the dimensions listed below. Mechanical and performance requirements for this part family are set by its own standards, not by the bolt and screw property-class documents.
ISO 4017 — Scope
ISO 4017 specifies the dimensional requirements for cylinder connecting sleeve — gb/t 5783 / iso 4017 (series 013). Material, surface condition and any performance rating are set by separate documents specific to this part family — ISO 898-1 and ISO 898-2, which govern bolt and nut property classes, do not apply here.
Tolerance & Product Grades
Tolerances for cylinder connecting sleeve — gb/t 5783 / iso 4017 (series 013) are given as limits on the individual dimensions in the table rather than as a fastener product grade. Where a general-tolerance class is cited on the drawing instead, it applies to the dimensions not otherwise toleranced.
Dimensions Specified by ISO 4017
| Size designation | Outer diameter / width (mm) | Length / height (mm) | Bore / thread (mm) | Material | Reference standard |
|---|---|---|---|---|---|
| Size 1 | 10 | 20 | 6 | C45 carbon steel | GB/T 1804-m |
| Size 2 | 12 | 25 | 8 | C45 carbon steel | GB/T 1804-m |
| Size 3 | 16 | 32 | 10 | C45 carbon steel | GB/T 1804-m |
| Size 4 | 20 | 40 | 12 | C45 carbon steel | GB/T 1804-m |
| Size 5 | 25 | 50 | 16 | C45 carbon steel | GB/T 1804-m |
| Size 6 | 32 | 63 | 20 | C45 carbon steel | GB/T 1804-m |
| Size 7 | 40 | 80 | 25 | C45 carbon steel | GB/T 1804-m |
| Size 8 | 50 | 100 | 30 | C45 carbon steel | GB/T 1804-m |
Equivalent Standards
ISO 4017 (full thread) corresponds closely to DIN 933; the partially-threaded variant ISO 4014 corresponds to DIN 931.
When to Specify ISO 4017
Choose ISO 4017 for international engineering work and OEM supply where ISO standards are the contractual reference. It is the default modern specification for cylinder connecting sleeve — gb/t 5783 / iso 4017 (series 013).
