The following chart is intended only as a starting point in the selection of fasteners. The fastener must be<br />
matched to the properties of the material. Drive to strip ratios, clamp retention, and other per<strong>for</strong>mance issues<br />
are directly affected by the fastener you choose. Please contact an <strong>Infastech</strong> applications engineer <strong>for</strong><br />
assistance in selecting the optimum fastener <strong>for</strong> your design.<br />
