Common Applications for M5 Clamping Handle Screw (Long) — DIN 6336 / GN 313 (Series 044)
M5 Clamping Handle Screw (Long) — DIN 6336 / GN 313 (Series 044) are commonly specified for precision instruments, small machinery and consumer-electronics enclosures.
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.
When to Step Up or Down from M5
When the joint preload approaches the proof load of M5 class 8.8, step up to M6 class 8.8 (or move to M5 class 10.9). When the joint is over-specified, M4 often saves weight and cost without losing the safety margin.
