CSK Post Head Anchor M5–6.5 × 23 316 (Single)

This M5–6.5 × 23 CSK Post Head Anchor is crafted from premium 316 marine-grade stainless steel, providing excellent corrosion resistance in outdoor, coastal, and marine environments. The countersunk (CSK) head allows the fastener to sit flush with the surface, creating a clean and professional finish ideal for balustrade posts, stainless fixtures, and architectural hardware.

The M5–6.5 sizing means the anchor features an M5 internal female thread with a 6.5 mm outside diameter body. This design allows a male-threaded fastener to be inserted from the opposite side, forming a concealed and secure connection with no exposed threads on the visible surface.
These anchors are also commonly referred to as sex bolts or mating bolts due to their male–female fastening structure.
