The ST-38 heavy steel framing nail serves professional framers who regularly work with extra-thick or multi-layered moulding profiles. Its 36.7 mm total length offers maximum mechanical bond strength without the need for adhesive in most applications.
Applications for ST-38 Nails
Barn wood frames, reclaimed timber artwork, wide shadow boxes, and thick gilded mouldings all benefit from the ST-38’s extended penetration depth.

Pre-clamp moulding corners with a frame vise before nailing to ensure a tight mitre join, especially in hardwoods where spring-back is common.
