A pulse tool has the speed of an impact wrench with nearly the repeatability of a clutch based shut-off tool. Containing precision-machined parts the pulse unit is a sealed chamber that is filled with a formulated hydraulic fluid. Pulse blades with a custom designed precision roller push the fluid inside the rotating chamber generating hydraulic…
You’ve probably heard a lot about stainless steel this and that. But what’s the big deal about stainless steel — and when do you need to choose stainless steel fasteners for your project? First let’s examine what goes into stainless steel that makes it, well, stainless. Ordinary carbon steel met the world’s steel needs for…
Every year at this time, I remind my family and our family of Mountz employees how much I love Thanksgiving. I’m sure they are tired of hearing it, but it’s true – I love Thanksgiving. Thanksgiving to me means family, something near and dear to most everyone. Our kids come home from college more thankful…
Choosing a socket for a power tool might seem like a simple task. Open any tool catalog or tool chest, find the correct drive size, select the hex size you need – and off you go. But it’s not that simple. The socket is often the most overlooked component when properly installing fasteners with power…
In nearly every heavy industrial application, turning threaded fasteners – nuts and bolts – is generally viewed by two criteria: (1) the need to fasten tightly enough to prevent movement of parts and achieve a good seal without exceeding the fastener’s elasticity level, and (2) successful removal of fasteners after long periods of environmental exposure…
From tightening large industrial bolts used in windmill gearbox assemblies to bolting maintenance applications for oil & gas pipelines and rigs, the Mountz electric torque multipliers achieve precision torque in a quick, cost-efficient manner. The electric torque multiplier shuts-off when pre-set torque is achieved. It’s a non-impacting and operates at a smooth, continuous rotation; the…
Generally, in the majority of applications, the reliability of the joint is dependent upon the bolts ability to clamp the parts together. Adequate clamping prevents relative motion between parts of the joint and leakage from joints containing gaskets. Measuring a bolts clamp force is difficult, especially under production assembly conditions. The clamp force generated by…
If in a plug-type screw connection the nut is gradually tightened more and more firmly, then the resistance increases steadily until a threshold is reached at which the screw begins to lengthen at which the screw begins to lengthen permanently. At this stage, even a weak force suffices to lengthen it even further. The tightening…
