 Screw
 Deformation
Body
 Cracks
 Dents
 Widening of the

 Dented or scuffed
screw holes
Inspection procedure
 Visually check the appearance of the
clamp.
 If a fault is found
as a result of the
visual check,
disassemble and
check the clamp.
Max working load and
manufacturing No.
 Check for the existence of an arc
strike. (Refer to JIS Z3001-2601.)
 Check to see if the screw cap and the
cam are tilted to the specified angle
and also rotate smoothly.
 Confirm that the screw is not bent,
deformed, dented, or cracked, and
operates
smoothly. If
it does not
operate
smoothly,
disassemble
Cam
and check
the clamp.
 Check visually for deformation, cracks,
dents, widening of the open part, and
wear of the rear.
 Wear of the suspension holes
 Dented or scuffed screw hole
 If the open part has widened, measure
it with a vernier caliper
 If you suspect that a clamp is cracked,
subject it to a penetrant inspection or a
magnetic particle inspection.

 Do not use a clamp
that has any of the
following defects:
 A clamp whose open
part is significantly
deformed, cracked,
widened, or worn
 A clamp whose
suspension holes are
significantly worn
 A clamp whose screw
hole is significantly
dented or scuffed
