Hallde Blender SB-4 screw size
M4 / M5 · 8 to 12 mm long
Our records put Hallde Blender SB-4 on M4 and M5 screws in lengths from 8 to 12 mm.
There are 2 separate fitment records for it, including M4 x 8, M4 x 10 and M4 x 12 stainless screws for housing, PC board and countersunk positio (M4) and screw MRT M5 x 12 A4 Torx T25 (x6) in the lid / camshaft support assembly (M5).
Head and drive, as the sources state them: flat / countersunk head and Torx T25 drive.
2 of the 2 records are marked confirmed, drawn from 1 source (hallde.com).
For reference, M4 is 4 mm across the threads at 0.7 mm pitch. The imperial size people confuse it with: #8-32 (4.17 mm) — the standard US PC/rack screw, close but not the same.

How to check the screw before you buy
- A screw that is even 1 mm too long in a laptop base can push into the keyboard, battery or a board trace, so match the length position by position.
- Diameter: across the threads an M4 screw measures about 4 mm with calipers (usually a hair under). This device also uses M5, so measure each screw rather than assuming they match.
- Pitch: 0.7 mm from one thread crest to the next (14.29 crests per centimetre). A thread pitch gauge or the pitch-gauge tool settles it in seconds.
- Length: the source describes a countersunk (flat) head, and those are measured overall, from the top of the head to the tip.
- The records span 8–12 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source names a Torx T25 drive. For comparison, standard M4 heads take PH2 (Phillips) or T20 (Torx), or a 3 mm hex key.
- Tightening: no device-specific torque is published in these records. The site's general figure for M4 is about 2.0-3.0 N·m into metal threads and 0.8-1.4 N·m into plastic bosses; snug it up and stop.
Common mix-ups with M4 / M5
- US-made pinball machines (Williams/Bally/Stern) overwhelmingly use imperial UTS threads (#6-32, #8-32, #10-32); explicit metric threads only appear on newer/import components such as Jersey Jack Pinball's Hobbit Smaug assembly (M3).
- M4 and 6-32 UNC share a nominal diameter with different pitch — a classic cross-thread in US-market kits.
- M5x0.8 is the de facto universal bike thread — confirm 0.8mm pitch before threading into carbon or alloy bosses.

Questions about Hallde Blender SB-4 screws
- What size screw does Hallde Blender SB-4 use?
- M4 × 8–12 mm for M4 x 8, M4 x 10 and M4 x 12 stainless screws for housing, PC board and countersunk positions; M5 × 12 mm for screw MRT M5 x 12 A4 Torx T25 (x6) in the lid / camshaft support assembly.
- How long are the screws in Hallde Blender SB-4?
- The records range from 8 to 12 mm depending on the position, so match each screw to its own hole.
- What is the thread pitch of an M4 screw?
- 0.7 mm (coarse), which is the standard pitch for M4 machine screws; a 0.5 mm fine pitch exists but is uncommon. The tap drill is 3.3 mm and the normal clearance hole is 4.5 mm.
- What screwdriver do I need for Hallde Blender SB-4?
- The source lists a Torx T25 drive. Standard M4 heads otherwise take PH2 (Phillips) or T20 (Torx), or a 3 mm hex key.
- Can I use an imperial screw instead of M4?
- No. Imperial look-alike: #8-32 (4.17 mm) — the standard US PC/rack screw, close but not the same. Use a true M4 screw so it does not cross-thread or strip the hole.
