DPX16 | DIA | #180/24

DPx16 DIA (also known as 135x16 DIA or 135x17 DIA) are industrial sewing machine needles specialized for heavy-duty leather, vinyl, and thick fabric projects. They feature a diamond-shaped cutting point (DIA) designed to slice through materials, creating straight, consistent seams. These needles are widely used in leatherworking and upholstery, offering superior performance compared to regular point needles.

Key Characteristics and Usage:
Needle System: 135x16 DIA, also referred to as DPx16 DIA or 135x17 DIA.
Point Style: DIA (Diamond Point/Wedge Point) - designed to penetrate tough materials without causing damage, preventing "blowout" on the back side.
Applications: Specifically for sewing leather, suede, vinyl, and, occasionally, hard, dry materials like paperboard.
Compatibility: Fits most walking foot and heavy-duty industrial sewing machines that accept 135x16 or 135x17 needle systems.
Common Sizes: Available in various sizes, with 140/22 and 180/24 being common for heavy materials.
