Conformance to the Bondhus® specification means that qualified technicians perform constant inspection, testing, evaluation, and adjustments to insure that the ‘no compromises’ policy is always adhered to. Bondhus does over 60 separate tests to guarantee that every tool manufactured is 100% within spec and worthy of carrying the Bondhus® name.

Sharp edges are critical to the tool fitting properly in a fastener. Rounded corners are not accepted. They will cause slippage and failure. Bondhus maintains the toughest standards in the industry.

Grain size is monitored before and after heat treating. A small grain size helps assure conformance to strength and hardness standards.

Cracks, decarburization, seams, surface discontinuities, undisolved carbides, and inclusions are not unusual in common grades of steel. These conditions cause poor ductility and premature tool breakage. The Protanium® steel specification, however, does not allow for these conditions to exist.

Hardness and Ductility Protanium® Steel is considerably harder than the steel produced by most Bondhus® competitors. When competitors do have hardness values approaching that of Protanium® steel, they do so by sacrificing ductility.

Ductility is important to monitor, since as the hardness increases, so does brittleness and the potential for shattering. Every batch of Protanium® steel is tested by applying torque in a standard break test. The Bondhus® standard assures in excess of 99% of all breaks will actually break clean and straight. Most competitors cannot even hit 50% clean breaks. Tools that shatter are a hazard to both the user and equipment in the vicinity.

Hardness testing is performed during and after the heat treating process to accurately measure and constantly monitor hardness values.

Torsional tensile strength is monitored for every batch of steel. An ongoing effort is made to improve strength and reduce or eliminate shattering. The heat treating process is adjusted for every batch of steel to obtain maximum ductility and hardness. Extensive lab testing has proven that Bondhus® tools consistently generate up to 20% more torque than any other manufacturer in the industry.
