Overview
The Beechcraft structural bolt, designated P/N 012-028, serves as a critical fastening component within the airframe assemblies of the T-34 Mentor. This specific hardware item is designed to secure various structural and non-structural elements, ensuring the mechanical integrity and safe operation of the aircraft. As a standard AN-series equivalent, this bolt provides robust connection points, resisting shear and tensile forces encountered during flight operations and ground handling.This particular bolt is typically found in applications where a 3/16-inch diameter fastener with a 3/8-inch grip length is required, often paired with appropriate washers and nuts to complete a secure joint. Its role is fundamental in maintaining the structural cohesion of the aircraft, from control surface attachments to internal airframe bracing. Proper selection and installation of P/N 012-028 are paramount for upholding the T-34 Mentor's airworthiness.Specifications
