Alden Wrench Sets - SAE and Metric
Most wrenches are made of hardened vanadium carbon alloy steel. Alden Wrench is made of Stainless Steel (17-4pH). This stainless alloy is widely used in aerospace and in many industries. It's limited hardening capacity, usually up to 38R.C. and rarely 40R.C., makes it an ideal stainless steel tool.

Most wrenches are mass produced and chrome plated. Alden Wrench has NO chrome nor cadmium plating, a basic requirement for use in aerospace. Chrome plating creates a shiny and appealing look when new. However, it will eventually form chrome chips when the tool ages. Chrome chips can interfere with sensitive mechanical and electrical function.

The shine you see with the new Alden Wrench is a result of hand polishing. Yes, all Alden Wrenches are individually hand polished. Although easier scratched compared to chrome plated wrenches, the shine can always be brought back by re-buffing the Alden Wrench. Most open ratchet wrenches need an open room or swing angle of 60 degrees to work. AldenWrench needs only 30 degrees room to ratchet. No other wrench even comes close. Coupled with a small head size and a design with increasing interactive grip it sets a new standard in the open end ratchet system.

In order to work, wrenches should be very hard and form a close tolerance fit with it's equivalent fastener size. Alden Wrench does not need the hardness of most commercially available wrenches. It is usually softer by -1to -2R.C. Why? It's unique interactive design creates a prying-like action of a fulcrum that transfers the force applied to the handle as a gripping action to the fastener. How? Because it grips more as more force is applied to the handle, it's grip is better than most regular open wrenches.
