Get quoteThe ST-18 steel framing nail is the go-to fastener for picture framers who demand precision and consistency. Manufactured from high-carbon steel, each nail features a 17.4 mm total length and a sharp tapered point that drives cleanly into frame stock without pre-drilling.
Frame joining requires a nail that holds firmly without cracking delicate moulding. The ST-18’s 2.3 mm wire diameter strikes the ideal balance between holding power and minimal wood displacement.
Total length: 17.4 mm | Wire diameter: 2.3 mm | Head width: 6.3 mm | Head thickness: 1.7 mm | Quantity: 400 pcs/box | Weight: 228 g/box | Boxes per carton: 20.
These nails are widely used in framing workshops, art galleries, and cabinet shops for joining mitered corners and securing backing boards. They are compatible with standard pneumatic ST nailers.
Set your nailer pressure between 60โ80 PSI for optimal countersinking without over-driving. Always test on scrap moulding before production runs.
Pair these nails with our framing staples for complete frame assembly solutions. For more information on professional framing hardware standards, visit the Professional Picture Framers Association (PPFA).
