Description
Overview:
The Shield Anchor - Loose Bolt, Size: M8 x 25 (Hole Size: 14mm), is a mechanical masonry fixing for secure, reliable anchoring in solid materials. Made by Mason Mate, it uses a four-piece segmented steel shield with a captive expansion cone that grips the sides of the drilled hole as the bolt is tightened. This loose bolt design lets you place the fixture first and tighten afterwards for accurate alignment. Suitable for brick, concrete, and natural stone, it is commonly used to fasten brackets, plates, racking, and frames. The M8 thread suits standard hardware, while the compact 25mm bolt length helps where space is tight. Sold individually, it is a practical choice for trades and DIY work where dependable holding power is required.
