Lycoming 31C-13 Stud is a precision-engineered engine hardware component designed for use in compatible Lycoming aircraft piston engines. This threaded stud provides a secure mounting point for engine components, allowing proper attachment and alignment of associated hardware assemblies.

The 31C-13 stud features a 5/16 inch diameter with a length of 1.63 inches, providing the required thread engagement and clamping capability for its designated engine application. Studs are commonly used in aircraft engines where secure fastening, accurate positioning, and resistance to vibration are essential.

Manufactured for aviation engine service, this stud is designed to withstand the mechanical loads, vibration, and temperature conditions present during normal piston engine operation. Proper installation torque and inspection procedures help ensure reliable retention of attached components throughout the engine service period.

The stud should be inspected during engine maintenance for damaged threads, corrosion, stretching, or other signs of wear. Replacement of compromised hardware helps maintain proper assembly integrity and supports continued engine reliability.
