These 10mm spacers are crafted from tough POM (polyoxymethylene, also known as Delrin). They're perfect for mounting accessory plates to 2mm frames. The package includes 4 spacers and 8 bolts with 2 spares. You can choose between nylon and steel bolts. Nylon bolts need more careful handling but offer a significant weight reduction.

Using these 10mm spacers is easy. First, pick the bolts you like - nylon or steel. If you choose nylon, handle them gently as they're more delicate. Then, place the spacers where you want to mount the accessory plates on the 2mm frames. Next, use the bolts to secure everything in place. When it comes to maintenance, keep the spacers and bolts clean. If you're using steel bolts, check them for rust occasionally. For nylon bolts, avoid exposing them to harsh chemicals. Store the product in a dry place when not in use to ensure its long - term performance.
