Yes, you can switch back and forth between millimeters and inches just by pushing a button.
Does the Insize 1112 caliper have data output?
Yes there is a data output on the Insize digital calipers 1112 series but this is an option and you will need to buy the accessory data out cable/system.
Is the Insize 1112 caliper water or coolant resistant?
No. The 1112 Series is not watertight or coolant proof. Keep the caliper dry for best results, but if you operate in a damp environment or with coolant, you should choose an IP rated digital caliper.
Does the caliper power off automatically?
Yes, the caliper features an auto power-off function that saves battery life, and it turns back on once the sliding unit is moved.
What battery is used in the Insize 1112 Series?
The Insize digital vernier caliper 1112 Series uses a CR2032 or LR44 battery, depending on the dispatch batch. Please check the battery compartment before buying new batteries.

Digital Vernier Caliper INSIZE 1108 Series can be used to check the external dimensions of shafts, rods, plates, blocks and manufactured components. The smaller upper jaws are used for checking internal dimensions such as hole diameter, slot width, and other openings. The integrated depth rod allows users to measure holes, grooves, recesses and cavities. Step measurement can also be made when the difference between two surfaces needs to be checked. For more stable depth readings, the optional 6140 depth base attachment can be fitted.
This four-way measuring capability makes the 1108 Series useful when different dimensional checks need to be carried out with one instrument.
Clear Digital Measurement with Data Output
The LCD screen displays the readings directly, so you don’t have to interpret the scale markings. This is especially useful for repetitive inspection work where you need to take measurements frequently during a production or quality-control process. The 0.01 mm resolution allows for fine dimensional checking and the mm/inch conversion means that measurements can be taken to match both metric and imperial engineering drawings.
The data output function enables you to transfer the readings to a computer or quality system, instead of writing down the readings. The optional 7315-25 transmitter provides wireless transfer to a receiver. The calliper also automatically turns off when not in use and turns back on when you move the slider, a feature which assists in saving the CR2032 battery.
Stainless-Steel Measuring Body
The product adopts stainless steel as the main measuring body; Rigid construction assists in maintaining the same position of the jaw throughout routine measurements, and is also suitable for industrial environments. Its smooth sliding action allows easy alignment of the movable jaw against a workpiece before taking the measurement. Kindly note: The 1108 Series does not qualify as waterproof, keep away from water and cooling fluid.

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
