Dependable Wing MountingSafe Fastening for Model Aircraft Wings
The Socket Head Bolts with Nylon Washers provide an ideal mounting solution for secure wing holddowns on your favorite RC airplane. Designed specifically for applications where traditional steel washers could crush or damage delicate surfaces, the nylon washer distributes pressure evenly while the steel socket head bolt ensures a tight lock. Keep your model aircraft wings safe and firmly anchored during flight with this essential hardware set.
Essential Hardware ProtectionEngineered Fastening for Delicate RC Airframes
When constructing or maintaining model aircraft, choosing the proper mounting hardware is critical for long-term airframe integrity. Using standard metal washers directly against wood, fiberglass, or foam wing mounts can cause crushing, gelcoat cracking, or stress fractures. The Socket Head Bolts with Nylon Washers solve this problem by pairing a non-marring nylon washer with a high-strength socket head cap bolt. Ideal for RC wing holddowns and other sensitive mounting locations, these socket head bolts allow for proper torque without surface damage, ensuring your model stays structural and flight-ready.

Frequently Asked QuestionsEverything you need to know
Why should I use Socket Head Bolts with Nylon Washers instead of standard steel washers for wing holddowns?
Steel washers can easily crush balsa wood, foam, or fiberglass wing structures when tightened. The nylon washers included with the Socket Head Bolts with Nylon Washers cushion the surface and distribute pressure evenly, preventing cracks while maintaining a strong grip.
Are Socket Head Bolts with Nylon Washers suitable for glow and gas RC airplanes?
Yes, Socket Head Bolts with Nylon Washers work great across electric, glow, and gas model aircraft where strong, non-marring, and vibration-dampening fasteners are required.
What tool do I need to install Socket Head Bolts with Nylon Washers?
You can easily install them using a standard hex key (Allen wrench) matching the socket head bolt size, ensuring a secure grip that won't slip or strip.
