Product Information

Regularly inspecting and replacing the hardware on critical portions of your vehicle's suspension, engine, and brake components is important for safety and stability, as well as maintaining the serviceability of your vehicle's common wear systems.

In certain applications on many European makes and models, bolts will be torque to yield and are specifically called out to be replaced once removed and not reused. When replacing a component, it's important to refer to the factory service procedures to determine an application fastener type, grade, installation torque values, and replacement recommendations

• Failure: Damaged hardware can fail under pressure, which can lead to engine damage, suspension component failure, and added wear
• Corrosion and rust: Over time, nuts and bolts can corrode or rust, which weakens them and increases the chance of failure
• Fatigue: Fasteners can fatigue due to exposure to debris, corrosion, water, and other contaminants. This fatigue can be caused by cyclic stress due to loss of initial pre-load

About Lisle

Founded in 1903, C.A. Lisle started the company with the first product being horse-powered water well drilling machines. On the off season to the well drilling business, they manufactured washing machines, cream separators, and push-type reel lawn mowers. In the mid-20s, Lisle Corporation made its first automotive product, a master ignition vibrator for Ford Model T vehicles. The first Lisle tool, a valve refacer, fast became a repair shop must since valves were reground every 20,000 miles at that time. In the 1930's they also manufactured magnetic oil drain plugs that were used in WWII for military equipment resulting in the Army/Navy E Award for manufacturing excellence in supporting the war effort. In the 1950's after the war, the automotive aftermarket boomed and demand for specialty automotive tools increased. It was then that the Lisle Corporation made the decision to grow the company by introducing new tools that could be made in the company's own factory, thereby controlling quality, delivery and costs. Today the company's tool line consists of more than 400 products of which most are produced at the original location, now expanded, in Clarinda, Iowa.
