GN 923 and 924 Flat-Faced Aluminum Handwheels

We're pretty excited about our new series GN 923 and GN 924 Flat-Faced Aluminum Handwheels, a new modern design that has us quite impressed.

GN 923 handwheels are solid disk, while GN 924 are two-spoked. Both types are available with or without revolving handles, as well as in versions with recessed locking retractable handles and recessed safety retractable handles. All types are RoHS compliant and come in both inch and metric sizes.

These handwheels are distinguished by their modern, flat-faced design and their recessed handles. The handwheel body is pressure die-cast aluminum with powder coated matte black pebble finish or silver textured finish. Rim is concentric and square to bore. The revolving handle is matte black nylon plastic hand piece with zinc plated steel threaded spindle. The removable plastic cover shrouds the assembly hardware such as screws and countersunk washers, as well as the shaft end.

How to Punch a Square Hole in Sheet Metal

My weekly googlings recently turned up a fun reference to J.W. Winco. Apparently our website was used as a source for an eHow article on punching square holes in sheet metal.

The key to the whole business, as so often in life, is having the right tool. If you happen to have a punch press and a square punch and die set, you’re good to go. But if you only need to punch a couple of holes on the rare occasion, that’s a prohibitively expensive investment.

The answer is our series GN 123 sheet metal punch, pictured here. This hardened steel punch is capable of penetrating sheet metal up to 2 mm thick. GN 123 punches are available in two sizes, to create square holes that will accommodate 14 or 22 mm.

We offer this tool in conjunction for use in installing our door locks GN 115, GN 115.1 and GN 119. But as the eHow article explains, some automotive parts require a square pass-through hole in either a sheet metal panel or other metal component.

After marking the center of the spot where you want the hole (using black marker on a piece of masking tape), you’ll need to drill a pilot hole. The mandrel of the punching tool is inserted in the pilot hole. You’ll use a ratchet wrench with the punch to drive the square die through the sheet metal.

Complete instructions are here.

GN 743.6 Metric Sized ATEX Explosive Protective Fluid Level Sight Glasses

Today we're showing off our new series GN 743.6 Metric Sized ATEX Explosive Protective Fluid Level Sight Glasses.

The RoHS-compliant sight glasses have a body of turned aluminum, bright finish, an ESG scratch-proof glass sight glass, a stainless steel retaining ring, and a seal of FPM rubber (Viton®).

These sight glasses are suitable for use in explosion risk environments, and comply with European 94/9/EG guidelines. They are sealed with an O-ring on the periphery and not on the face edge of the glass. Leak tightness is therefore not affected by axial pressures. The seal is housed in a groove and therefore cannot be lost. Meanwhile, this groove prevents the seal from being extruded when the sight glass is tightened. The location of this seal also allows the use of a softer Elastomer, guaranteeing better and easier sealing. Cold/heat resistance range is -20°C (-4°F) to 150°C (300°F).
