S:FLEX Hanger Bolt / Solar Fastener System screw size
M6 · length not stated in the sources
Our records put S:FLEX Hanger Bolt / Solar Fastener System on M6 screws. None of the sources we found gives an exact length, so measure the original before you order.
Where it is used: hanger bolt fastening system for PV module racking on trapezoidal sheet metal roofing.
This entry is marked reported and comes from sflex.de.
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
- Rack and enclosure hardware mixes metric and imperial (#8-32, #10-32, #6-32), so confirm the thread before forcing a screw.
- 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
- 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.
- VESA displays over 50kg move up to M8 x 1.25, which is outside metric M6 hardware - don't force an M6 bolt into a heavy-panel mount.

Questions about S:FLEX Hanger Bolt / Solar Fastener System screws
- What size screw does S:FLEX Hanger Bolt / Solar Fastener System use?
- M6 for hanger bolt fastening system for PV module racking on trapezoidal sheet metal roofing.
- How long are the screws in S:FLEX Hanger Bolt / Solar Fastener System?
- 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 S:FLEX Hanger Bolt / Solar Fastener System?
- 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.
