304 Stainless Steel Expansion Anchor Bolts High Strength Galvanized Mechanical Expansion Screws

These 304 stainless steel expansion anchor bolts are designed for mechanical anchoring applications where a strong connection is required between the fixture and the base material. The anchor is inserted into a pre-drilled hole and tightened so that the expansion section expands against the inner wall of the hole, creating a firm mechanical lock.

The checked product title identifies the material as 304 stainless steel and describes the product as high strength and galvanized. 304 stainless steel provides good corrosion resistance and is widely used for hardware, construction, equipment fixing, and general industrial fastening. The galvanized surface description indicates a protective finish for improved surface durability and appearance.

This expansion fastener is suitable for applications such as automotive repair, machinery installation, brackets, base plates, wall fixtures, equipment supports, and construction hardware. The product can be used where ordinary screws cannot provide enough holding strength and where an expansion-style anchor is needed.
