The 5010236 is a Pipistrel internal part number referring to a hex-head structural bolt used in light aircraft assembly. This type of fastener is a standard aerospace-grade hexagon head bolt designed for load-bearing mechanical joints where high shear and tensile strength are required, typically in airframe, structural brackets, engine mounts, landing gear attachments, or primary load transfer points depending on the aircraft configuration.

Unlike button-head or low-profile screws (such as ISO 7380 types), hex-head bolts are used in higher-load structural applications where tool access and torque control with a wrench or socket are preferred over low-profile aesthetics. These bolts are commonly specified in aviation-grade standards (e.g., DIN/ISO equivalents or aerospace-specific specs), with material selection typically driven by strength-to-weight and corrosion resistance requirements.

In Pipistrel aircraft systems, such bolts are usually used in conjunction with self-locking nuts, washers, or bonded inserts in composite structures. Material variants often include high-strength steel (e.g., 8.8 / 10.9 / 12.9 class), stainless steel for corrosion resistance, or occasionally titanium in weight-critical assemblies.

Proper installation requires correct torque application and often torque-seal marking or inspection procedures in aviation maintenance to ensure continued structural integrity under vibration and cyclic loads.
