Hillman Corrugated Joint Fasteners 30 Count

These corrugated bright steel fasteners join corner pieces in woodworking projects where the backside appearance is not a concern. The thin strips are designed to be hammered directly into hard or soft wood joints for a secure hold. Suitable for DIY repair, furniture assembly, or shop use where visible finish is secondary to joint strength.

3/8 Inch Height 5 Gauge Steel Construction

The single specification that determines fit is the 3/8 inch height combined with 5 gauge steel thickness, which dictates the joint depth and material density the fastener can penetrate. This specific profile ensures the strip drives correctly into the workpiece without splitting the wood or bending during installation. Verify your joint thickness matches this height before purchase.

Bright Finish Steel for Structural Use

The bright steel finish indicates no protective coating, meaning these fasteners are intended for interior or concealed applications where corrosion resistance is not required. The 30 count pack provides sufficient quantity for multiple corner joints or small production runs without needing to reorder immediately. They are not suited for visible surfaces or outdoor exposure.

Questions about this item

What does the 3/8 inch height mean when the fastener is driven into a wood joint?

The 3/8 inch height is the depth the corrugated steel strip penetrates into the wood when hammered in, providing the holding power for the joint.

What does the 5 gauge steel thickness limit in terms of the wood you can use it on?

The 5 gauge steel is thick and stiff, so it requires a solid hammer blow and is best suited for harder woods or thicker stock that will not split under the driving force.

What physical space is needed to hammer these corrugated fasteners into a corner joint?

You need clearance for a hammer swing directly over the joint line, and the wood pieces must be thick enough to accept the 3/8 inch penetration without the fastener protruding out the opposite face.
