Loose Fasteners: Problems and Solutions for Maintenance and Quality Control

July 11, 2017 02:36 AM


Accidents never happen without a cause.
And they do happen particularly in the busy day-to-day operations of a high-volume assembly plant.

Seemingly minor accidents (such as a power tool slipping off a fastener and marring a Class A finished surface) can cost an assembler thousands of dollars annually…


Vibration, expansion, contraction and corrosion can create side to side thread movement which leads to lossening and ultimely fastener failure. Therefore, assemblies have to be frequently checked and retightened.


Fortunately, there are ways to protect assemblies from accidental dings and scratches. A small investment in preventive detection can save assemblers thousands in repair bills.

Security Check Paint Marker is an inspection marker which delivers a pasty paint. Paint is applied on the assembly. Once dried the film becomes hard like stone. If loosening happens, the paint will break and a simple visual inspection will alert that the part has moved from its original position.

Easy to use for a quick detection !
