This is a high - quality replacement kit ideal for HBM front lights like V521s HBM and E3 Pure 3 HBM. The set includes 1x M6 screw x 0.75, 1x washer, and 1x adapter washer, ensuring a perfect fit for your front lights.

Using this screw set is easy. First, remove the old screws from your HBM front lights. Then, use the included M6 screw x 0.75 to secure the light, add the washer for a snug fit, and the adapter washer if needed. When installing, make sure not to overtighten the screw as it may damage the light or the mounting. For maintenance, regularly check the screws to ensure they are not loose. If the set gets dirty, you can clean it with a soft, dry cloth.
