Remove the bolt so the anchor is flush with your walls and floors to slide components past these anchors, making it easier to install or make adjustments. They’re best for door frames that need to be pressed into place or machinery you service frequently. All have a sleeve that expands inside your hole to create a strong grip. Since the gripping force is distributed along the entire length of the anchor, it won’t crack soft materials like block and brick. You can use these anchors as an alternative to wedge anchors in concrete near edges, corners, or other weak points, but they are not as strong.

To install, drive the anchor through your component into a drilled hole until the head meets the surface. Then, tighten the bolt to expand the anchor sleeve. As you tighten, the nylon ring compresses to secure the component against the surface. You can remove the bolt, but the anchor itself cannot be removed.

Join threaded studs and pins to metal surfaces in milliseconds, forming bonds stronger than the studs themselves. Just load a stud into the gun, aim it against your base material, and pull the trigger to fuse the two together.

Unlike drawn arc stud welders, our capacitor discharge systems work with metals less than a millimeter thick. They won’t leave fastener heads on the opposite side of the base material, so they’re often used for jobs requiring a clean-looking finish, such as attaching handles to high-end cookware. The one-sided welds are also preferred by the USDA for fabricating dairy tanks and other food-safe machinery – with no holes drilled, germs have nowhere to hide.

A go and no-go gauge in one, these gauges check that left-hand threads fall within tolerance. Use them to confirm thread fit for nuts, tapped holes, and other parts. The taperlock handle speeds up tests, giving you a good grip to thread and unthread each gauge end. It also lets you swap out worn gauges for new ones (not included) on either end.

The go gauge checks the minimum internal thread size, and the no-go gauge checks the maximum. A part is within tolerance if it’s easy to thread the go gauge but difficult to thread the no-go gauge more than two turns.

Speed up thread tolerance checks—the handle on these gauges gives you a good grip to quickly thread and unthread go or no-go gauges. Use these gauges to make sure nuts, tapped holes, and other parts fall within tolerance. All are precisely manufactured to confirm thread fit. If the plug gauges wear down, you can insert new ones (not included) onto the taperlock handle.

A part is within tolerance if it’s easy to thread the go gauge into the part but difficult to thread the no-go gauge more than two turns.

Go/no-go gauges have both a go gauge on one end of the handle and a no-go gauge on the other to speed up tests. Go gauges check the minimum internal thread size. No-go gauges check the maximum internal thread size.
