Common Applications for M10 Swing Bolt — GB/T 77 / ISO 4026 (Series 020)
M10 Swing Bolt — GB/T 77 / ISO 4026 (Series 020) are commonly specified for general-purpose machinery, jigs, fixturing and light structural connections.
Mating Parts for M10
For M10, pair with a M10 hex nut (ISO 4032 / DIN 934) and, where used, a M10 flat washer (ISO 7089 / DIN 125A) under the head and under the nut.
When to Step Up or Down from M10
When the joint preload approaches the proof load of M10 class 8.8, step up to M12 class 8.8 (or move to M10 class 10.9). When the joint is over-specified, M8 often saves weight and cost without losing the safety margin.
