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.

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 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.
