How to Choose the Correct Screw
How to Choose the Correct Screw
Selecting the correct screw is important for proper fit, strength, and long-term reliability. Before ordering, confirm the following:
Screw Size (Diameter)
Measure the outer thread diameter of the screw. Metric screws are labeled in millimeters, such as M2, M2.5, or M3.
Length
Measure from under the head to the tip of the screw unless otherwise specified by the head style.
Thread Type
Ensure the thread matches the receiving material. Most electronics and hardware applications require metric machine threads rather than self-tapping threads.
Head Type
Confirm the head style needed for proper seating, such as flat head, pan head, or button head.
Drive Type
Match the drive type (Phillips, Torx, Hex, etc.) to the tools you plan to use and the torque requirements of the application.
Material & Finish
Choose the appropriate material and finish based on strength, corrosion resistance, and environmental conditions.
If you are replacing an existing screw, we recommend removing one and comparing the diameter, length, and head type directly before ordering to ensure a proper fit.
