I already use a loose nut indicator. Why do I need Zafety Lug Lock®?
Loose lug nuts are a serious safety issue and it continues to be important to be concerned about them. Wheels come
off when the vehicle is in motion – the indicators cannot help the driver when the vehicle is moving. The product you are
using only warns of the problem after it occurs and it may be missed for some time as it requires human intervention to
stop any serious problem from happening. Zafety Lug Lock® minimizes the risk of a loose nut problem because even
improperly torqued nuts are prevented from loosening. If a stud and nut shears off the wheel, Zafety Lug Lock® may
retain the sheared component versus the loose nut indicator which will fly off with the stud down the road. Zafety Lug Lock® is a wheel nut retainer not just a wheel nut indicator.
I don’t get many loose nuts so I don’t think I need your product.
It only takes 1 loose nut to stress the entire wheel end and risk more nuts coming loose. Studies show that loose wheel
nuts are responsible for 66% of wheel separations. That one loose nut could result in in a tragic and costly accident.
How much torque can a piece of plastic stand up to before the nuts start to loosen?
Nuts come loose due to vibration working the nut back along the stud. In fact, there is no significant reverse torque that
contributes to loosening of the nut. Zafety Lug Lock® is design engineered with a high strength to weight ratio, and the
design has been proven in independent vibration testing to retain lug nuts from rotating in operating temperatures
ranging from -40⁰F (-40⁰C) to +320⁰F (+160⁰C).
How do I know that Zafety Lug Lock® will really prevent the lug nuts from loosening?
Numerous fleets over the last eight years have confirmed the product really works. An internationally respected test
laboratory was engaged to test Zafety Lug Lock® and their reports confirm the effectiveness of Zafety Lug Lock® in
preventing nuts from coming loose. Field testing by a customer in conjunction with a third-party engineering firm at the
Bosch road testing facility in Indiana also confirmed that Zafety Lug Lock® really does keep lug nuts from loosening.
My concern with these type products is that we must remove them to do our scheduled torque checking then re-install them. This takes too much time and adds to the cost.
The good news is you can complete a nut torque check without removing Zafety Lug Lock®. All those other products
need to be removed. An independent test study confirmed that re-torqueing without removing Zafety Lug Lock® did not
affect the performance of the product and had no effect on the physical quality of the unit.
Looks like a great product but how easy are they to install and remove?
Zafety Lug Lock® can be installed or removed by hand or with a specially designed tool in a matter of minutes for all the
wheels of your vehicle. We recommend they be at shop or room temperature for the easiest installation.
Can this product stand up to exposure of the harsh operating environment of chemicals, diesel fuel, brake fluid and other fluids my equipment needs?
Zafety Lug Lock® is a design-engineered plastic typically used in automotive products that are constantly exposed to
chemicals commonly found in road salt, liquid calcium chloride, hydraulic fluid, transmission fluid, windshield washer
alcohols, gasoline and diesel fuel, iron oxides, radiator fluid, locktite, ethanol alcohol.
