FUJILOK Nuts:
FUJILOK Nuts:
Have wide temperature range for applications—
Low Carbon Steel: -30°C to +250°C
High Carbon Steel: -50°C to +350°C
Stainless Steel: -100°C to +350°C
The AISI-301 Stainless Steel inserts are not affected by
alcohol, gasoline, oil or commercial solvents.
FUJILOK Nuts: Seating of nut is not necessary for locking action. Nut will
lock on bolt when a minimum of one bolt thread extends
above nut.
See following page C27 for list of stock sizes of FUJILOK Nuts.

TS = TENSILE STRENGTH OF BOLT, MINIMUM
YS = YIELD STRENGTH OF BOLT, MINIMUM
The torque figures in this chart when used as recommended above should result in a fastener tension
which is equal to 60% of the ultimate yield strength of the fastener material, and the coefficient is 0.2.
They are computed using the following formula:
T = 0.2(0.6 x Óy) x As x d + RT
Where T = Torque figures Óy = Ultimate tensile strength As = Tensile stress area
d = Nominal size RT = Run-down torque
The torque figures are suggested to be increased for a given job as much as 80% or more for stainless
steel above those figures in the chart, as the material is stressed less than those fasteners made of
steel.
