Parafuso sextavado Roadinger M10x50 FK8.8 zincado

Hex bolt Roadinger M10x50 FK8.8 zinc-plated is a metric fastener designed for general fastening tasks in construction, machinery and repair work. It features an M10 threaded diameter with a 50 mm shank length and strength class FK8.8, finished with a zinc plating that provides basic corrosion resistance. The bolt is intended for applications that require medium tensile strength and reliable clamping of metal and structural components.

Advantages

This Roadinger hex bolt offers standardized metric threading for compatibility with common nuts and tapped holes, and strength class FK8.8 delivers a balance of tensile strength and toughness for many mechanical and structural joints. The zinc-plated surface reduces surface corrosion under normal indoor and sheltered outdoor conditions, extending service life compared with uncoated steel. The hex head allows for straightforward installation with standard spanners, sockets or wrenches, ensuring secure and consistent torque application.

Key specifications

How to use

Select an appropriately sized nut or tapped hole matching the M10 metric thread and ensure mating parts are correctly aligned. Insert the bolt through the components to be fastened and hand-start the nut to avoid cross-threading. Tighten using a hex spanner, socket or torque wrench to the recommended torque for FK8.8 M10 bolts for your specific application and material; avoid over-tightening to prevent thread or material damage. If reusing the bolt, inspect for thread wear or corrosion and replace if any deformation or significant corrosion is present.

Recommendations

Use in environments with limited exposure to moisture or corrosive chemicals; for long-term outdoor or marine exposure consider higher-grade corrosion protection or stainless alternatives. Match the bolt strength to the application's load requirements and use appropriate washers and locking methods where vibration or dynamic loads are present.
