How long are the screws in EM-Tec SEM sample holders?

The records range from 4 to 6 mm depending on the position, so match each screw to its own hole.

What is the thread pitch of an M1.6 screw?

0.35 mm (coarse), which is the standard pitch for M1.6 machine screws; a 0.2 mm fine pitch exists but is uncommon. The tap drill is 1.25 mm and the normal clearance hole is 1.8 mm.

What screwdriver do I need for EM-Tec SEM sample holders?

The source lists a Hex socket (Allen) drive. Standard M1.6 heads otherwise take PH00 (Phillips) or T4–T5 (Torx), or a 1.5 mm hex key.

Can I use an imperial screw instead of M1.6?

No. Imperial look-alike: #1-72 UNF (1.85 mm) is larger; there is no true imperial equivalent. Use a true M1.6 screw so it does not cross-thread or strip the hole.

Where can I buy replacement screws for EM-Tec SEM sample holders?

TechSpareWarehouse (our own store) lists M1.6 x 4mm, which matches the length in the records above.

EM-Tec SEM sample holders screw size

M1.6 · 4 to 6 mm long

Our records put EM-Tec SEM sample holders on M1.6 screws in lengths from 4 to 6 mm.

The record covers M1.6C replacement socket cap screw set, M1.6x4mm and M1.6x6mm stainless.

Head and drive, as the source states them: socket cap head and Hex socket (Allen) drive.

This entry is marked likely and comes from microtonano.eu.

M1.6 means a 1.6 mm nominal diameter with a 0.35 mm thread pitch. Imperial look-alike: #1-72 UNF (1.85 mm) is larger; there is no true imperial equivalent.

How to check the screw before you buy

Keep material and finish the same as the original (often stainless) on equipment that is cleaned or sterilised.
Diameter: across the threads an M1.6 screw measures about 1.6 mm with calipers (usually a hair under). If yours measures noticeably more or less, it is a different thread.
Pitch: 0.35 mm from one thread crest to the next (28.57 crests per centimetre). A thread pitch gauge or the pitch-gauge tool settles it in seconds.
Length: for socket cap screws, measure from under the head to the tip (countersunk heads are the exception: they are measured overall).
The records span 4–6 mm, which means different positions take different lengths — match each hole to its own screw.
Driver: the source names a Hex socket (Allen) drive. For comparison, standard M1.6 heads take PH00 (Phillips) or T4–T5 (Torx), or a 1.5 mm hex key.
Tightening: no device-specific torque is published in these records. The site's general figure for M1.6 is about 12-20 N·cm into metal threads and 6-10 N·cm into plastic bosses; snug it up and stop.
