Selection Guide

Selection Checklist

1. Choose the fastener typeDecide whether the assembly requires screws, nuts, or matching components in the same thread size.
2. Confirm the metric threadMatch the existing threaded hole, nut, insert, or drawing before selecting a screw length.
3. Select screw lengthFor screws, consider joined thickness, required engagement, washers, recesses, and available clearance.
Applications

Typical Application Areas

Research InstrumentsNon-metallic fastening for housings, brackets, covers, and internal support structures.
Electrochemical FixturesPeripheral fastening around laboratory fixtures and fluidic components.
Analytical EquipmentAssembly of laboratory modules, detection platforms, and instrument accessories.
Electrical IsolationPrototype structures where non-metallic fastening components are preferred.
Microfluidic PeripheralsMounting around interface plates, supports, and modular fluidic hardware.
Laboratory Spare PartsMultiple metric sizes support practical maintenance and spare-part stocking.
FAQ

Frequently Asked Questions

Why do nut rows not include a length?

The available nut data is organized by metric thread size. No separate nut-length field is provided for this series.

Can screws and nuts be ordered together?

Yes. For paired procurement, list the screw size and length together with the quantity of matching nuts required.

How should a screw model such as M10×60 be read?

M10 is the metric thread size and 60 is the nominal screw length in millimeters.

What should be reviewed for demanding applications?

Consider load, tightening method, temperature, chemical exposure, electrical isolation, cleanliness, and long-term mechanical stress for the complete assembly.

Purchase FAQ

Frequently Asked Questions

Why do nut models not have a length field?

Nuts in this model set are selected by metric thread size; a separate length value is not supplied for these nut records.

Can a screw and matching nut be purchased together?

Yes. Use the same metric size and list the required screw length plus nut quantity.

Are the USD values final checkout prices?

They are reference prices for comparison. Marketplace pricing, shipping, taxes, quantity, and availability may change.

Can I request a mixed-size quotation?

Yes. Send a list of product type, metric size, screw length where applicable, and quantity for each line item.
