Common Applications for M6 Hex Head Bolt, Fully Threaded — GB/T 5783 / ISO 4017 (Series 012)
M6 Hex Head Bolt, Fully Threaded — GB/T 5783 / ISO 4017 (Series 012) are commonly specified for general-purpose machinery, jigs, fixturing and light structural connections.
Installation Tips for M6 Hex Head Bolt, Fully Threaded — GB/T 5783 / ISO 4017 (Series 012)
- Use a 6-point socket where access allows — 12-point sockets are more prone to rounding the corners on smaller sizes.
- On flanged or serrated variants, do NOT add a separate flat washer — the flange already spreads the load and the washer can defeat the locking serrations.
Mating Parts for M6
For M6, pair with a M6 hex nut (ISO 4032 / DIN 934) and, where used, a M6 flat washer (ISO 7089 / DIN 125A) under the head and under the nut.
