WABCO 85mm twin air compressor head/cover kit screw size
M6 · length not stated in the sources
WABCO 85mm twin air compressor head/cover kit takes M6 metric screws. None of the sources we found gives an exact length, so measure the original before you order.
It is listed for torque instructions state: 'Remove the six M8 (13mm across hex frets) head bolts and seven M6 screws' referring to the compressor's cover screws distinct from the M8 head bolts.
This entry is marked confirmed and comes from fleet-products.ca.
M6 means a 6 mm nominal diameter with a 1 mm thread pitch. 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
- If several screws hold the same part, check that they are all the same length before assuming they are.
- 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.
- 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
- Astro dovetail hardware is inconsistent: Losmandy-brand dovetail plate screws are 1/4-20 (imperial) per Losmandy/Astro-Physics documentation, while PrimaLuceLab's PLUS-standard dovetails explicitly use M6 — don't assume metric across all 'Losmandy-style' dovetail ecosystems.
- 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.

Questions about WABCO 85mm twin air compressor head/cover kit screws
- What size screw does WABCO 85mm twin air compressor head/cover kit use?
- M6 for torque instructions state: 'Remove the six M8 (13mm across hex frets) head bolts and seven M6 screws' referring to the compressor's cover screws distinct from the M8 head bolts.
- How long are the screws in WABCO 85mm twin air compressor head/cover kit?
- None of the sources states a length. Remove one screw and measure it from under the head to the tip (overall for a countersunk head).
- 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 WABCO 85mm twin air compressor head/cover kit?
- 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.
