There are many shapes of metal anchors, such as Y-shaped, V-shaped, T-shaped, S-shaped, etc. (see Figure 1). Metal anchors are refractory castables, refractory plastics and refractory spray coatings used to support and fix thinner liners. Which shape of metal anchor to use depends on the structure of the lining. The shape of the Ceramic Anchor is shown in Figure 2. The upper and lower ends must be flat, and the remaining 4 sides are toothed to increase the occlusal area and friction with the lining body, and play a role of suspension and support Alloy Anchors,Y Anchors,Studs Anchors,Aluminum Alloy Anchors Puyu kiln technology (jiangsu) CO.,LTD , https://www.anchorpy.com
**DIN933 A2-70 Stainless Steel Hex Machine Bolt**
A machine bolt is a type of threaded fastener with an external male thread. It is often confused with screws, but it typically requires a nut to secure two or more components together. A hex cap screw, which is similar to a hex bolt, has a hexagonal head designed to be tightened with a wrench or spanner. However, ASME B18.2.1 compliant cap screws have tighter tolerances for the head height and shank length compared to standard hex bolts. This means that while a hex cap screw will always fit in a location designed for a hex bolt, the opposite may not always be true.
