www.GarvinIndustries.com – 2-1/2″ uninsulated set screw electrical connectors are used in dry locations to bond 2-1/2″ EMT thinwall conduits to electrical junction boxes or enclosures. Garvin Industries’ uninsulated steel set screw connectors provide concrete tight connections when taped and properly secured with the included locknut, and are rated for electrical applications above 600 volts. Their heavy gauge steel construction maintains mechanical protection and solid grounding of the conduit to the designated electrical junction box or enclosure. Additionally, set screw connectors are zinc electroplated for excellent corrosion protection. Set screw connectors are also made with a versatile combination head screw that can securely fasten a conduit to an electrical junction box using a slotted, Phillips, or Robertson head screw driver.

I’ve been asked to build a bunch of cutting boards and I wanted to experiment with an easier way to clamp multiple strips with ease.
Two pieces of 3/4” MDF glued together and the end pieces were just scrap four be two’s. 1/4 threaded insertion nuts and 1/4” X 4” machine screws for the clamping force. It worked well for a test and I have a few ideas to improve thing on the next try. The bolts wanted to move the strip of aluminum around until it had a bit of pressure on it but it was manageable. Just regular packing tape to protect the base. When it was fully clamped, I flipped it over and check to see if it was flexing or bowing. It was less than a half a mm and that could just be the variance in the MDF itself.
