Technical Performance
The ARRMA Cap Head Screw 3x8mm is engineered with precision tolerances to meet automotive-grade fastening standards. The M3 metric size refers to a 3mm nominal diameter shaft with a standard machine thread pitch, creating secure engagement with ARRMA's pre-drilled threaded inserts and holes throughout the 4x4 chassis. The 8mm length provides the correct fastening depth for ARRMA's assembly design, ensuring proper load distribution and preventing over-tightening or under-fastening scenarios. The hex socket drive with cap head design distributes stress evenly across the fastening point, critical for maintaining structural integrity in high-vibration environments typical of RC 4x4 off-road driving. The black finish indicates standard-grade fastening with robust corrosion resistance suitable for both indoor and outdoor use. When properly installed with appropriate torque, these screws maintain clamping force through repeated assembly and disassembly cycles, making them ideal for regular maintenance routines essential to RC car ownership in the UK.
