Get quoteThe ST-18 Steel Row Nail Box Pneumatic Pin from Chaoyue (???/STAFDA) is a professional heavy-gauge pneumatic nail with a 2.3mm thick shank, 17.4mm total length, and a wide 6.3mm flat head. It is engineered for demanding picture frame assembly, solid wood panel fastening, and dense substrate pinning where lighter brads fail.
At 2.3mm diameter, the ST-18 is significantly heavier than standard F-series brads. The larger shank cross-section resists pull-out forces in dense hardwoods, engineered lumber, and thick MDF โ making it the professional’s choice for solid wood picture frames and heavy furniture joints.
Total length: 17.4mm | Shank diameter: 2.3mm | Head diameter: 6.3mm | Head height: 1.7mm | Qty: 400 pcs/box | Weight: 228g | Boxes per carton: 20 | Material: hardened steel.
The ST-18 Steel Row Nail Box Pneumatic Pin is available in 20-box cartons for workshop bulk purchasing, providing 8000 nails per carton.
Solid hardwood picture frame corner pinning, dense MDF panel joining, heavy timber furniture frame assembly, structural casing attachment, and display fixture construction where maximum nail cross-section is needed.
Step up to the ST-25 (24.1mm length) for greater depth, or to ST-32 (31.3mm) for the heaviest frame work. For F-series brads see F20 Straight Nail.
