Product DescriptionThere are several types of expansion bolts
available, including mechanical, and undercut anchors. Mechanical
expansion bolts use a wedge or tapered shape to create a secure
hold within the material. Undercut anchors use a special drilling
technique to create a larger hole in the material, allowing the
sleeve to expand even further for a stronger hold.Expansion bolts
are commonly used in construction and engineering applications
where a secure hold is required. They are easy to install and can
be used in a variety of materials, including concrete, brick, and
stone. Product Name: Hexagon NutsQuality hex nutss are
