Countersunk Sleeve Anchors
When installing countersunk sleeve anchors, it is essential to consider the base material's thickness and the length of the anchor needed to achieve optimal expansion and clamping force. The plastic collar, included with some anchors, aids in pulling down small gaps and exerting a positive clamping force. Countersunk sleeve anchors are commonly used in construction and anchoring applications, providing a medium-duty solution for attaching fixtures and fittings to solid base materials.
It is important to note that the availability of specific countersunk sleeve anchor sizes and materials may vary among suppliers, and it is always recommended to consult with a trusted supplier or manufacturer to ensure the selection of the most suitable anchor for the intended application.
