K187142 Rolls-Royce Bolt | Qty 10 | New Old Stock

The K187142 Rolls-Royce Bolt, offered as a quantity of ten (Qty 10) in New Old Stock (NOS) condition, is a precision aerospace fastener designed for use in approved aircraft engine and mechanical assemblies. Bolts used in aviation applications must meet exacting standards for strength, dimensional accuracy, and material integrity, as they play a critical role in maintaining structural security and system reliability.

Supplied as NOS, these bolts have not been previously installed or used in service. New Old Stock components are typically sourced from surplus or legacy inventories and remain desirable for aviation maintenance and restoration programs due to their unused condition and original manufacturing quality. When properly stored, NOS fasteners retain their mechanical properties and dimensional tolerances, making them suitable for professional aerospace use.

Part number K187142 is manufactured to precise specifications to ensure correct fitment and compatibility with approved assemblies. Aerospace bolts are engineered to withstand vibration, cyclic loading, temperature variation, and environmental exposure commonly encountered during aircraft operation. Proper bolt selection and installation are essential for maintaining clamp load, preventing loosening, and protecting mating components from damage.

This bolt is associated with hardware standards used in systems produced by Rolls-Royce, whose engines and components are widely deployed across helicopter and fixed-wing aircraft platforms. Hardware of this type is commonly installed during engine assembly, scheduled maintenance, repair, or overhaul activities where adherence to approved part numbers and configurations is mandatory.

The K187142 bolt set is well suited for MRO facilities, operators, and aviation parts distributors managing engine hardware inventory or supporting legacy Rolls-Royce engine platforms. Final installation and approval for service should always be carried out by qualified aviation maintenance personnel in accordance with applicable maintenance manuals, torque specifications, and regulatory requirements.

The Rolls-Royce Bolt K187142 (Qty 10, NOS) provides a dependable fastening solution for aerospace applications where precision, durability, and compliance with approved standards are essential.
