Precision Matters Best Practices for Using Manual Threaded Insert Tools

SELF TAPPING THREADED INSERT
MANUAL INSTALLATION TOOLS

For strong, reliable insert installation, using the correct manual tool and drill diameter is essential.
Our manual threaded insert installation tools are designed for versatility—perfect for prototyping, small-batch production, and field repairs.
Though diameter charts are available for reference, real-world results vary depending on material hardness, assembly force, and insert type. We recommend performing sample tests to find the ideal hole size.
Also, when installing into through-hole components, ensure the insert length is shorter than the material thickness to maintain proper anchoring and avoid surface damage.
★ Compact, durable, and user-friendly—our tools are a must-have for precise insert installation.
