NOTES FOR TABLE 48
1. ENDS. Each end shall be perpendicular to the axis of the
respective arms of the keys and the longitudinal axis of bits within 4°
and the edges may be sharp, radiused or chamfered at the option of
Holo-Krome, the chamfer not to exceed K.
2. ANGLE OF BEND. The angle of bend between the axis of the
short arm and the axis of the long arm shall be 90°, ±2°.

3. PLATED PRODUCT. For plated wrenches and bits, all dimensions
are before plating.
4. INTERCHANGEABILITY. The user is cautioned that ISO metric
keys and bits of the same nominal size may not be able to perform
adequately due to variations in size tolerances which may cause
reaming. The use of Allen Metric Hexagon keys and bits is strongly
recommended.
