The XA_RP012X087ZP is a precision-engineered spring roll pin (also known as a slotted spring pin) that compresses upon installation and expands to lock into place within pre-drilled holes. Suited for use in conductor-bar systems, it securely holds components such as collector shoes, pivot brackets, and splice parts under dynamic loads and vibration. Manufactured to spring-pin standards (e.g., ASME B18.8.2), this pin is typically made from carbon or stainless steel and finished to prevent corrosion and ensure reliable performance under repeated mechanical cycles Key Features 1/8_ _ 7/8_ dimensions — common size for C_Series application fitments. Spring roll (slotted) design — compressed during install, expands to self-lock, resisting loosening under vibration. asmc.net Constructed to ASME B18.8.2 standards — ensures consistency in diameter, chamfer, and fit. Durable steel material — often carbon or stainless steel with protective coating (e.g., zinc or natural finish). Reliable and reusable — can be driven out for maintenance and replaced with ease.
