The A-W Series™ Knurled Threaded Insert can be installed into most any material softer than itself that is thicker than .062/1,57. The A-W Insert provides exceptional shear strength and pull out in fiberglass and plywoods.

The brass A-W Insert is particularly useful for the fiberglass boat industry.

The A-W Insert is installed using lightweight, handheld Pneumatic Tools that can be located at any position in your product’s assembly sequence. The A-W Insert can be installed either prior to or after finish.

NOTE 1: Additional UNF thread sizes available. 
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.
