## Summary description

Seaming and Clinching Pliers 90° Bent Bessey D351-60 are hand-operated pliers with a 90° bent head designed for seaming, clinching and folding sheet metal edges. They provide precise mechanical control for joining or forming flanges and seams in sheet fabrication, HVAC work, metal trim and repair tasks where angled access is required.

## Long description

Seaming and Clinching Pliers 90° Bent Bessey D351-60 are hand-operated pliers with a 90° bent head designed for seaming, clinching and folding sheet metal edges. The tool provides controlled mechanical action for forming flanges, closing seams and creating tight folds in thin to medium gauge sheet metal. The bent head allows access to angled or confined areas, making the pliers suitable for on-site HVAC work, metal trim installation and repair tasks that require precise bending where a straight tool cannot reach.
Advantages
The 90° bent head gives improved access to corners and narrow spaces while preserving visibility of the work area. Hand operation ensures tactile control and incremental adjustment when forming seams or clinches. Hardened jaws and a robust lever mechanism deliver consistent bending force and long service life under regular workshop or field use. The compact form factor and one-handed operation facilitate positioning and holding folded flanges during assembly.
Suitable for
 Seaming and clinching thin to medium gauge sheet metal
 Forming and closing metal flanges and seams in HVAC ductwork
 Trim work, flashing and roof edge folding
 Repair work and on-site adjustments where angled access is necessary
When it may not be suitable
This tool is intended for manual forming of thin to medium gauge sheet metal and is not designed for heavy plate bending or large-scale metal forming. It may not deliver sufficient force for very thick or hardened steel, and using it on inappropriate materials can damage the tool or produce unsatisfactory results. For repetitive high-volume industrial production, powered or press-based equipment is likely more efficient.
Key specifications
 Tool type: Hand-operated seaming and clinching pliers
 Head: 90° bent head for angled access
 Primary use: Seaming, clinching and folding sheet metal edges
 Construction: Hardened jaws with lever mechanism for consistent force
 Handling: One-handed operation, compact design for confined spaces
How to use
Position the bent jaws over the sheet metal edge or seam, aligning the pliers so the bend follows the intended fold line. Squeeze the handles steadily to close the jaws and form the flange or clinch; release and reposition as needed to work progressively along the seam. For long seams, make a series of incremental folds rather than attempting a single large bend to maintain control and achieve an even result. Maintain a stable workpiece and, where practical, support the opposite side of the seam to prevent distortion.
What to consider before purchase
 Intended material thickness and type — suitable for thin to medium gauge sheet metal
 Need for angled access — the 90° head is designed for corners and confined areas
 Frequency of use — hand tool best for occasional or on-site tasks; heavy production may require powered equipment
 Compatibility with existing workflow and whether one-handed operation meets job requirements
Usage recommendations
Use steady, controlled strokes and work incrementally along seams to achieve uniform folds. Keep jaws clean and inspect for wear; do not use the pliers as a substitute for heavy bending tools. Store dry and oil pivot points occasionally to maintain smooth operation.
