Inspection Equipment
Aside from their main use as fasteners, screw parts also have various functions as components in assembled products. For example, they can be used as an axle for a rotating part, or as a position adjustors, and therefore their functionality as such also needs to be checked. It is also essential that they undergo inspections to ensure that they can withstand use in harsh environments, and that they do not cause damage to the environment. At Katayama Rivet & Screw, we use cutting-edge inspection devices and equipment to carry out these inspections and analyses.
Equipment and machinery
· Inspection laboratories
 Highly accurate measurement devices are needed to measure precision screws.
 Our inspection labs where this very sensitive equipment is housed are kept clean at all times and
 are temperature controlled.

· Image processing and measurement microscope
 Images of products that have been enlarged to 50 or more times their actual size are
 processed by computer to enable measurement. Images can be blown up to 4,800 times the actual size
 of the product to be viewed.
