Fastening regimes with multiple screws are susceptible to fastening failures such as cross-threading, cam-outs, stripped screws, omissions, and unfinished rundowns. A screw counting process is an error-prevention technique that allows an engineer to detect and eliminate costly screw-fastening errors during the assembly process. Monitoring the fastening process allows production managers to correct fastening errors rather…
Flat-pack furniture famously exported by Scandinavia offers practical lessons about the importance of assembly line ergonomics. Assembling the furniture doesn’t seem difficult, especially if you have your own power tools, along with the small disposable screwdrivers and hex keys that come with the furniture. However, once you have it assembled, you may find your hands…
The Scout screw counter is an error-prevention device that detects and eliminates costly screw-fastening errors during the assembly process. Using a screw counter is like putting the eyes and ears of a quality control manager where they are needed most – right in the assembly area. Fastener tracking devices, like a Scout screw counter, count…

For customers that depend on precision torque to ensure outstanding product quality, the Mountz FG preset hand driver redefines the hand tool experience. Engineered, designed, and assembled in the Silicon Valley by Mountz, The Torque…
Counting screws is not the new song title from the rock band “Counting Crows.” Screw counting is a quality control process utilized in the manufacturing environment. Tightening hundreds and hundreds fasteners daily, assembly operators can forget to fasten some screws here or there during the monotonous routine. For complex fastening regimes with multiple screws on…
A screw counter helps manufacturers detect and eliminate costly screw-fastening errors during the assembly process. Using a screw counter is like putting the eyes and ears of a quality control manager where they are needed most – right on the assembly area. The Scout screw counter from Mountz Inc. verifies that all fasteners have been…
Selecting the proper electric screwdriver for a fastening application can be a daunting task at times. So many options and features being offered in the torque tool market today. Understanding the technology and educating yourself about the various differences among the electric screwdriver technology is the important element in order to properly evaluate a tool…
Electric screwdrivers with brushless motors have an extremely long operating life with no need for regular maintenance or replacement of expendable parts (carbon brushes, rotor, switches and other contact points). Heat generated by the motor is reduced and screwdriver performance is always at the maximum level resulting in reliable product quality. The brushless electric screwdriver…
Solving fastening problems is about controlling variables or eliminating potential causes that create an unwanted fastening event. Let’s take a look at common unwanted fastening events. Cross threading, thread or component stripping, unseated fasteners, missing screws, nut or bolt (omissions) these are all evident events of failure that we can see with our eyes. Thank…
Joint relaxation occurs to some extent in all fastened joints. It is caused by the surface of part(s) embedding or by “soft parts” such as gaskets, plastics or spongy material, which collapses under the clamping force created in a torque fastening condition. For correctly designed joints, relaxation is small and can be virtually ignored. However,…
