This page covers M5 Clamping Handle Screw (Short) to DIN 6336 / GN 313: the full dimensional row, hole and tool sizes, proof-load data and typical applications. All values are taken from the governing standards (DIN 6336 / GN 313 together with ISO 273, ISO 724 and ISO 898-1 where applicable).
M5 Dimensional Row (DIN 6336 / GN 313)
| Thread size | Pitch (mm) | Length L (mm) | Handle length (mm) | Knob diameter (mm) | Reference standard |
|---|---|---|---|---|---|
| M5 | 0.8 | 20 | 45 | 28 | DIN 6336 / GN 313 |
Spanner & Drive for M5 Clamping Handle Screw (Short) — DIN 6336 / GN 313 (Series 042)
Drive geometry for M5 Clamping Handle Screw (Short) — DIN 6336 / GN 313 (Series 042) is given by the row above; match the tool to the listed values.
Hole Sizes for M5
| Coarse-thread pitch (ISO 724) | 0.8 mm |
|---|---|
| Through-hole / clearance (ISO 273 medium) | 5.5 mm |
| Tapping drill, coarse thread | 4.2 mm |
Tightening Torque for M5
| Class 8.8 (dry, ~µ 0.125) | ≈ 5.8 Nm |
|---|---|
| Class 10.9 (dry, ~µ 0.125) | ≈ 8.1 Nm |
| Class 12.9 (dry, ~µ 0.125) | ≈ 9.7 Nm |
Indicative dry-joint values. Lubrication can lower the required torque by 15–25%. Always confirm against the joint design, especially when going up a strength class.
Proof Load & Strength for M5
| Tensile stress area As (ISO 898-1) | 14.2 mm² |
|---|---|
| Proof load, class 8.8 | 8.2 kN |
| Proof load, class 10.9 | 11.8 kN |
| Proof load, class 12.9 | 13.8 kN |
| Min. ultimate tensile, class 8.8 | 11.4 kN |
Proof load = stress area × proof stress per ISO 898-1. Design joints so the working preload stays below the proof load of the selected class.
M5 Clamping Handle Screw (Short) — DIN 6336 / GN 313 (Series 042) Weight
A steel M5 clamping handle screw (short) at the listed 20 mm length weighs approximately 3.1 g each — about 3.1 kg per 1,000 pieces. Stainless A2/A4 weighs roughly the same (density 7.9–8.0 g/cm³). Actual weight varies slightly with head form, thread and finish; use this figure for freight estimation only.
Common Applications for M5 Clamping Handle Screw (Short) — DIN 6336 / GN 313 (Series 042)
M5 Clamping Handle Screw (Short) — DIN 6336 / GN 313 (Series 042) are commonly specified for precision instruments, small machinery and consumer-electronics enclosures.
Installation Tips for M5 Clamping Handle Screw (Short) — DIN 6336 / GN 313 (Series 042)
- At M5 the joint is sensitive to over-torque — use a torque-limiting driver and check the head doesn't bury into a softer counterpart.
Mating Parts for M5
For M5, pair with a M5 hex nut (ISO 4032 / DIN 934) and, where used, a M5 flat washer (ISO 7089 / DIN 125A) under the head and under the nut.
