3. What materials are ER40 spanners made from?ER40 spanners are usually manufactured from high-quality hardened steel or alloy steel. These materials provide excellent strength and durability, making the spanner suitable for frequent industrial use.
4. How do I use an ER40 spanner safely on a collet nut?Turn off the machine, hold the tool holder steady, and use the ER40 spanner to tighten or loosen the collet nut. Apply firm, even pressure—avoid over-tightening to prevent damage to the nut or collet.
5. Can I use a single ER40 spanner for different ER series nuts?No, ER spanners are size-specific. An ER40 spanner is designed exclusively for ER40 collet nuts. Using it on ER32, ER25, or smaller/larger sizes may result in improper grip and tool damage.

1. What is an ER16 Hex Nut used for?
An ER16 Hex Nut is used to securely clamp an ER16 collet in a CNC collet chuck. It applies uniform pressure to hold tools like end mills, drills, and taps during machining.
2. How is a hex nut different from a slotted nut?
A hex nut has an external hexagonal shape for tightening with a standard spanner or wrench, while a slotted nut uses internal grooves for a specialized spanner. Hex nuts are often preferred for quicker manual operation and torque application.
3. Is this hex nut compatible with all ER16 collet chucks?
Yes, the Block to Box ER16 Hex Nut is compatible with all ER16 standard collet chucks, including BT, CAT, ISO, and straight shank types.
4. What material is used for Block to Box ER16 hex nuts?
Our ER16 hex nuts are made from hardened alloy steel, surface-treated with a black oxide coating for wear and corrosion resistance.
5. Can I use this with automatic tool changers (ATC)?
Yes. These hex nuts are suitable for both manual and automatic tool changers, provided they match the machine’s collet chuck system.
6. Do you provide ER16 hex nuts in sets or with collet kits?
Yes. We offer individual units, bulk packs, and combo kits with ER16 collets and collet chucks. Contact
