Plunger splices are made by ______ or ______ them together.

Plunger splices are typically made by screwing or bolting them together. This method provides a reliable and strong connection, which is crucial in applications where safety and durability are paramount. Screwing allows for a tight fit and easy adjustment, while bolting can accommodate larger loads and stresses.

Utilizing mechanical fasteners like screws and bolts enables easier disassembly and maintenance compared to methods that involve welding or riveting. This is particularly beneficial in the context of jacks, where regular inspection and potential repair may be necessary. More permanent methods like welding or riveting may compromise the ability to disassemble the joint without damaging the components, which is not ideal for servicing needs. Thus, the approach of using screws and bolts aligns well with industry standards for maintainability and practicality.
