A double end stud, as its name implies, is a type of fastener that features two threaded ends with a unthreaded shank in between. This unique configuration allows it to serve as a versatile connector in a range of applications. Historically, the design of the double end stud emerged from the need for robust fastening solutions that could withstand significant stress and load. Its origins can be traced back to the industrial revolution when the demand for durable and reliable construction materials surged as industries expanded.

EPDM washered fasteners are specialized fastening solutions that incorporate EPDM washers as sealing components. EPDM is a synthetic rubber renowned for its excellent resistance to weathering, ozone, ultraviolet (UV) radiation, and various chemicals. When integrated with fasteners, EPDM washers enhance the performance of bolted joints by providing effective sealing, reducing the risk of leaks, and accommodating thermal expansion and contraction.
