ArmaCoil Insert Superiority

ArmaCoil Inserts provide positive means for protecting and strengthening all tapped threads. They are mirror-smooth, reinforced internal threads of cold rolled 18-8 stainless steel, or other space age material, with hardness far in excess of the usual tapped materials. The outstanding engineering features of ArmaCoil Inserts, long recognised by the leading aircraft, industrial and military equipment manufacturers, have established their widespread use in these fields. The many company standards and defence specifications for ArmaCoil Inserts also prove their wide acceptance.

Advantages of ArmaCoil Free Running and Screw-Lock Inserts

A	Protect tapped threads against wear and damage in all metals and their alloys - aluminium, magnesium, titanium, copper, steel, as well as in plastics and other materials.
B	ArmaCoil Inserts develop maximum clamping load and bolt tension through efficient use of applied torque. Their smooth rolled thread surface assures most effective use of high strength alloy steel bolts.
C	Weight saving is unmatched - an important design feature for many products, particularly airborne equipment.
D	They strengthen tapped threads by a more balanced distribution of dynamic and static loads for the full length of thread engagement. The flexibility of the insert compensates for lead and angle error and allows each coil to carry its share of the load.
E	The superior corrosion resistant characteristics of ArmaCoil Stainless Steel Inserts assure their adaptability to most materials and usual environmental conditions. Applications must be made consistent with good engineering practice as outlined in the design data. Where conditions warrant, other wire materials may be used such as phosphor bronze or Nimonic 90.
F	ArmaCoil Inserts provide maximum flexibility of design with the widest choice of materials for the component, the fastening and even the insert to meet performance and production requirements.
G	Overall product cost savings may be realised by using a less expensive material and still maintain required thread strength with ArmaCoil Inserts.
H	Cost savings apply in many directions - lower insert costs, lower installation costs and smaller bosses all produce savings.
I	Screw-Lock Inserts positively secure threaded members against loosening caused by vibration and shock. They have a high reusable factor due to the exclusive ArmaCoil Resilient Screw-Lock which permits frequent removal and reassembly of bolt without appreciable loss of torque.
J	Space saving is maximised, permitting the use of standard boss configurations with no over-size boss required - as is necessary to accommodate solid bushings. A boss radius equal to the nominal bolt size is adequate for most load conditions.
K	Lowest installed cost is realised with ArmaCoil Power Tools and Tape Feed - production rates up to 800 or more inserts per hour with little or no waste.
