Detailed Description
Hex Expansion Bolt with Red Nylon Washer (DIN9021, White Zinc Plating)
This is a hex expansion bolt featuring a red nylon washer, complying with DIN9021 standard, with white zinc plating on the surface. Mostly made of carbon steel, it’s used for fixing installations on concrete, brick walls, etc. (e.g., door/window, bracket mounting). The bolt tightens to expand the tube and lock it in place. The red nylon washer buffers and prevents scratches, while white zinc plating enhances rust resistance.
Instructions for Use:
Matching Check：Choose specs based on fixed object thickness & substrate; confirm DIN9021 compliance matches project needs.
Pre - use Inspection：Check for damage/deformation on the bolt, expansion tube, red nylon washer, and threads.
Installation Requirement：Drill a hole in the substrate, insert the bolt with the red nylon washer, then tighten the nut with a wrench. Ideal for concrete/brick wall fixings.
Force Application：Apply even force during tightening to avoid cracking the expansion tube or damaging the substrate. Over - force is prohibited.
Maintenance：Regularly check for rust, loosening, or washer deformation. Replace promptly if defects affect fixing performance.
