Non-Standard Car Hex/Cross-Recessed Seven-Tooth Armrest Screw

Non-standard screws for cars, usually used to fix armrests. The nut is hexagonal and the screw head is cross-grooved for easy installation and removal. The threaded part has seven teeth to ensure the firmness and stability of the connection. This screw material is strong and corrosion-resistant, suitable for armrest fixing needs of various models. It not only provides strong locking force, but also maintains good performance during frequent disassembly and assembly.
Traditional hex or cross-recessed designs only provide a few points of contact, while the seven-tooth design of the Non-standard car seven-tooth armrest screw provides more points of contact. By increasing the contact points, torque is more evenly distributed when tightening or loosening the screw, reducing localized stress concentrations and thereby reducing the risk of slippage or slippage between the screw head and wrench.
