sturiz 60Pcs M5 Bolts M5X20mm Flanged Button Head Socket Cap Screws Bolts Carbon steel Pan Head Screws Black Oxide Allen Bolts with Hex Drive for Table Legs Vehicles DIY Model Building

• 【Practical Kit】: You will receive 60 M5X20mm black head internal hexagonal M5 bolts with washers and a 3mm internal hexagonal wrench. M5 allen bolts diameter is M5 and the thread length is 20mm. This kit provides an adequate number of fasteners for installation and maintenance work that requires secure fastening.
• 【High-quality materials】: The hexagonal head fastening M5 bolt with washers inside are made of high-quality carbon steel. M5 allen bolts processed through heat treatment, featuring high hardness and strong tensile strength, which enhances the durability of the fasteners. The surface is treated with black oxidation, which effectively reduces rust and corrosion and presents a refined and beautiful appearance.
• 【Inner hexagonal design of the head】: The inner hexagonal M5X20mm bolt of the head adopts a cylindrical head design, with a hexagonal driving structure embedded inside. The force distribution is uniform, enabling it to withstand high torque tightening operations. When used in conjunction with standard inner hexagonal wrenches, the installation is convenient and stable, effectively preventing tool slippage, and the threaded connection is safe and reliable.
• 【Integrated gasket design】: M5 bolts 20mm adopt an integrated gasket design, which increases the contact area, reduces pressure, and effectively protects the surface of the fixed component. This design eliminates the need for separate installation of the gasket, significantly improving the assembly efficiency, while ensuring strong fastening stability and excellent anti-loosening effect, achieving more reliable connection performance.
• 【Widely applied】: 20mm bolts have a wide range of applications, covering fields such as furniture manufacturing, construction engineering, mechanical assembly, automotive repair, electronic equipment, and woodworking products. They not only meet industrial-level fastening requirements but are also suitable for DIY projects. They are ideal choices for various metal connections, wood fixations, and assembly operations.
