Description
Monster Overview:
Expansion Shield Anchors – Zinc Alloy from Monster Bolts are versatile, heavy-duty fasteners designed for concrete, brick, block, and masonry. Available in both single and double expansion versions, these anchors are engineered to provide a secure hold where vibration or shifting loads are a concern.
Available in sizes from 1/4" up to 3/4", these zinc alloy shields expand outward as the screw or bolt is tightened, gripping the base material tightly and preventing pullout.
Monster Features:
- Single Expansion: Provides a strong grip in solid materials; expands fully when tightened.
- Double Expansion: Ideal for softer or more unpredictable masonry; distributes load across anchor length.
- Material: Made from durable zinc alloy for strength and corrosion resistance.
- Applications: Use in block, brick, concrete, and masonry where secure anchoring is required.
- Sizes Offered: 1/4" through 3/4".
