Robotiq 2F-85 / 2F-140 gripper (Universal Robots) screw size
M6 · 12 mm long
Our records put Robotiq 2F-85 / 2F-140 gripper (Universal Robots) on M6 screws, 12 mm long.
It is listed for coupling-to-mounting-plate screws with tooth lock washers, and I/O coupling to flange.
This entry is marked confirmed and comes from assets.robotiq.com.
An M6 screw is 6 mm in diameter with a 1 mm pitch, tapped with a 5 mm drill; imperial look-alike: 1/4in-20 (6.35 mm) — the tripod/camera thread; visibly larger than M6.

How to check the screw before you buy
- Into printed plastic, the screw either self-taps or needs a heat-set insert; machine screws straight into plastic strip easily.
- Diameter: across the threads an M6 screw measures about 6 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
- Pitch: 1 mm from one thread crest to the next (10 crests per centimetre). A thread pitch gauge or the pitch-gauge tool settles it in seconds.
- Length: measure from under the head to the tip for pan, button, wafer and cap heads; countersunk (flat) heads are measured overall.
- The record states 12 mm. Going longer risks bottoming out or touching parts behind the hole; going shorter loses thread engagement.
- Driver: the source does not name the drive. Standard M6 heads take PH3 for Phillips and T30 for Torx, and a 5 mm hex key for socket heads; a bit that fits loosely will cam out and strip the head.
- Tightening: no device-specific torque is published in these records. The site's general figure for M6 is about 7-10 N·m into metal threads and 2.5-4.0 N·m into plastic bosses; snug it up and stop.
Common mix-ups with M6
- UR cobot flange bolts are commonly sold/quoted as 'M6 bolts' but the required length depends on the tool thickness; UR's own guidance is bolt class M6-8.8 to ISO4762 without a fixed length, so length must be selected per adapter/tool stack-up, not assumed as a fixed mm value.
- The same StarTech universal projector mount ships with M3, M4, M5, and M6 screw sets simultaneously so the installer can pick whichever matches the projector's own threaded inserts — metric size is projector-dependent, not mount-dependent.

Questions about Robotiq 2F-85 / 2F-140 gripper (Universal Robots) screws
- What size screw does Robotiq 2F-85 / 2F-140 gripper (Universal Robots) use?
- M6 × 12 mm for coupling-to-mounting-plate screws with tooth lock washers, and I/O coupling to flange.
- How long are the screws in Robotiq 2F-85 / 2F-140 gripper (Universal Robots)?
- The record gives 12 mm. Measure the original from under the head (overall for a countersunk head) to confirm before ordering.
- What is the thread pitch of an M6 screw?
- 1 mm (coarse), which is the standard pitch for M6 machine screws; a 0.75 mm fine pitch exists but is uncommon. The tap drill is 5 mm and the normal clearance hole is 6.6 mm.
- What screwdriver do I need for Robotiq 2F-85 / 2F-140 gripper (Universal Robots)?
- The sources do not name the drive. For M6, Phillips heads normally take PH3 and Torx heads T30; socket heads take a 5 mm hex key.
- Can I use an imperial screw instead of M6?
- No. Imperial look-alike: 1/4in-20 (6.35 mm) — the tripod/camera thread; visibly larger than M6. Use a true M6 screw so it does not cross-thread or strip the hole.
