Shackles are U-shaped pieces of metal secured with a pin or bolt across the opening, or hinged metal loops that are secured with a quick-release locking mechanism

Lifting blocks are assemblies that consist of a hook or shackle, swivel, bearing, sheaves, sprockets, pins and frame.

Form gages and form gaging systems are used to inspect parameters such as roundness, angularity, squareness, straightness, flatness, runout, taper and concentricity.

Surface profilometers are contact or non-contact instruments used to measures surface profiles, roughness, waviness and other finish parameters.

Semiconductors (metalloids) or semiconductor materials are used to fabricate microelectronic and optoelectronic devices such as transistors, photodetectors or solar cells.

Surface metrology equipment is used to measure the surface finish and/or geometry of engineering components.

Retaining rings and snap rings are fasteners used to axially position a component on a shaft or in a bore.
