All materials for the A-W Series® are plated
cadmium and look similar. Radial grooves are
machined into the part for material identification.

NOTE 2: HOLE SIZE: The A-W Series® Insert hole size will be dependent on parent material density. Experimentation is required for optimum performance.
NOTE 3: FINISH: The standard specified finishes for the A-W Series® Insert are cadmium and tin. Alteration to these finishes will reduce performance.
*THREAD CLASS: The A-W Series® Insert‘s internal threads are manufactured oversized to compensate for resulting thread portion shrinkage during the installation swaging process. They are not gaugeable prior to or after installation but will be compatible with Class 2A/3A or 6g screws after installation.
