Product Overview

Metric PEEK Fasteners for Research and Instrument Assembly

From compact M2 and M2.5 sizes through M10 and M12, the range provides a wide combination of metric thread sizes and lengths for systematic selection.

145 Standard Specifications

Thread Size × Length Selection

Specifications are organized by metric thread size and nominal length. Start with the mating threaded hole or nut, then select a length that provides suitable engagement without interfering with surrounding components. The broad size matrix supports compact laboratory hardware, instrument structures, fixtures, and non-metallic fastening positions.

Selection Guide

How to Choose the Correct Screw

1. Confirm the thread sizeMatch the existing threaded hole, nut, insert, or design drawing before selecting length.

2. Confirm the required lengthConsider joined-part thickness, washers, recesses, required thread engagement, and available clearance.

3. Review service conditionsFor meaningful mechanical load, elevated temperature, chemical exposure, or repeated cycling, review the complete fastening condition before use.

Applications

Typical Application Areas

Research InstrumentsFastening of covers, brackets, frames, mounting plates, and internal supporting structures.

Electrochemical HardwarePeripheral fixture and component assembly where a non-metallic fastener is preferred.

Analytical EquipmentAuxiliary fastening for laboratory modules, test platforms, and instrument structures.

Microfluidic PeripheralsMounting of interface plates, valve supports, brackets, and surrounding mechanical structures.

Electrical IsolationPrototype and educational assemblies requiring non-metallic fastening hardware.

Custom Laboratory FixturesBroad thread and length coverage supports multi-level fixture and prototype selection.

FAQ

Frequently Asked Questions

How should a size such as M4×10 be read?

M4 identifies the metric thread size and 10 identifies the nominal screw length in millimeters.

Which parameter should be selected first?

Confirm the mating thread or nut size first, then select the screw length according to the assembled thickness, thread engagement, washers, and available installation space.

Can PEEK screws be substituted directly for metal screws?

Dimensional compatibility alone does not establish mechanical equivalence. Load, tightening method, temperature, chemical exposure, and long-term stress should be reviewed for the complete assembly.

Can multiple sizes be ordered together?

Yes. For mixed-size or project orders, list each thread size, length, and quantity separately for efficient quotation and confirmation.

PURCHASE & TECHNICAL SUPPORT

Purchase & Technical Support

Standard configurations can be selected by thread size and specification. For mixed-size orders, project quantities, or application-specific requirements, include the requested model, dimensions, quantity, operating environment, and mating components so the selection can be reviewed efficiently.

Ordering Guide

Purchase & RFQ Recommendations

Use the full size codeSpecify dimensions in the M-thread × length format, such as M4×20 or M10×60.

List each quantity separatelyFor mixed-size orders, provide the quantity required for each individual size.

Include application conditionsState temperature, medium, load, isolation, cleanliness, or other requirements that may affect selection.

Purchase FAQ

Frequently Asked Questions

Are the displayed prices final checkout prices?

The listed values are reference prices for model comparison. Marketplace pricing, shipping, taxes, quantity discounts, and availability may vary at the time of purchase.

How should I choose between thread sizes?

Confirm the mating threaded hole or nut first. A screw with the correct length but the wrong metric thread size is not compatible.

Can multiple lengths be purchased together?

Yes. Mixed-size and project orders can be quoted from a consolidated list containing specification, quantity, and application requirements.

What should I provide for a technical selection check?

Provide the intended thread size, required length, quantity, mating component, operating environment, and any special mechanical or chemical requirements.
