| Designing
With Yardley® Inserts |
| Cored or machined
holes should be the correct size for the insert used. If the hole
is too large, there is a reduction in stripping torque and pull-out
force. For optimum performance, the boss diameter should be twice
that of the insert diameter. A larger boss diameter increases
the stripping torque. Please consult our engineering department for
specific recommendations on your applications. |
