Get quoteThe 20mm Mini Concrete Fastener Pin (W07) is a premium powder-actuated fastener designed for professional construction applications. Engineered to exacting tolerances, the 20mm Mini Concrete Fastener Pin delivers consistent, reliable performance in concrete, masonry, and structural steel substrates.
The 20mm Mini Concrete Fastener Pin features a hardened steel body with a gold-plated finish that resists corrosion and reduces friction during firing. With a total length of 20mm, a 7mm cap diameter, and a 3mm working tip diameter, the W07 is optimised for use with standard powder-actuated tools.
Professional installers rely on the 20mm Mini Concrete Fastener Pin because it offers predictable embedment depth, reduced spalling, and consistent holding strength across varying concrete grades. The red plastic guide washer ensures accurate positioning and prevents lateral movement during firing, making every shot count.
The 20mm Mini Concrete Fastener Pin is suitable for a wide range of jobsite tasks including structural steel framing, metal track attachment, conduit and cable clip fastening, and insulation board anchoring. Its 20mm length provides the ideal balance of penetration depth and material holding capacity for most standard construction assemblies.
Understanding the full specification of the 20mm Mini Concrete Fastener Pin ensures correct tool selection and compliance with structural requirements. Key parameters include a 20mm total length, 7mm cap diameter, and 3mm working diameter โ all consistent with industry-standard powder-actuated fastener dimensions.
The 20mm Mini Concrete Fastener Pin is available in a box quantity of 160 pieces, with a total package weight of 300g. This bulk-friendly format reduces downtime on high-volume projects and ensures you always have the right fastener to hand.
Always ensure the 20mm Mini Concrete Fastener Pin is used with a compatible, calibrated powder-actuated tool. Refer to the tool manufacturer’s load chart for correct charge selection based on substrate type and hardness. Operators should wear appropriate PPE including safety glasses, hearing protection, and steel-toed boots.
