What makes the Alden wrench different?
1. Our wrenches are made of Stainless Steel (17-4pH).
Most wrenches are made of hardened vanadium carbon alloy
steel. 17-4 stainless steal is widely used in aerospace and many other
industries. Its limited hardening capacity (usually up to 38R.C. and rarely
40R.C.) makes it an ideal stainless steel tool.
2. Most wrenches are mass produced and
chrome plated.
Our wrenches are not chromed nor cadmium plated, which is a
basic requirement for aerospace industry use. Chrome plating creates a shiny and
appealing look when new. However, chrome chips will eventually form from tool
usage. Chrome chips can interfere with sensitive mechanical and electrical
function. The shine you see on our wrenches are a result of hand polishing. All
wrenches are individually hand polished. Our wrenches may scratch somewhat
easier compared to chrome plated wrenches, however re-buffing can always bring
back the shine.
3. Our wrenches do not need the hardness of most
commercially available wrenches.
In order to work, wrenches should be very hard and form a
close tolerance fit with its equivalent fastener size. Our wrenches are softer
by -1 to -2R.C. Their 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. Because they grip increasingly more as more force is
applied to the handle, they grip better than most regular open-end wrenches.
4. Our wrenches need only 30º of room to ratchet.
Most open-end wrenches need a minimum of a 60º swing angle
to ratchet. Our wrench requires only half of that at 30º of swing because of the
patented design. Coupled with small head size and a design with increasing
interactive grip---it sets a high standard in the open-end ratchet system.
