Leather sewing needles SINGER 250054403 size 90/14 pack of 5 for machine stitching leather and heavy materials

Pack of 5 SINGER leather sewing needles size 90/14 for machine stitching leather and heavy materials. These needles are designed with a reinforced point and a thicker shaft to penetrate tough fabrics cleanly, reduce bending and breakage, and produce consistent stitch quality when used in compatible domestic or industrial sewing machines. The set is intended for tasks that require a robust needle able to handle dense or layered materials while maintaining reliable machine performance.

Advantages

These leather sewing needles offer a reinforced tip and a sturdy shaft that improve penetration through leather, vinyl, canvas and other heavy materials. The thicker construction reduces needle flex and the risk of breakage during high-tension or multi-layer stitching. Designed for machine use, they provide consistent stitch formation and longer service life compared with standard needles when working with dense textiles and coated materials.

Suitable for

• Sewing repairs on leather garments and accessories
• Production and repair of bags, belts and wallets
• Upholstery and furniture leatherwork
• Sewing heavy fabrics such as canvas, denim and coated textiles
• Home and light industrial machine stitching of layered materials

Key specifications

• Needle type: leather/motorized sewing machine needle
• Size: 90/14 (medium-heavy thickness)
• Quantity: pack of 5 needles
• Point: reinforced/sharpened for penetrating dense materials
• Shaft: thicker construction to resist bending and breakage

How to use

Install the needle with the flat side (if present) positioned according to your sewing machine manufacturer’s instructions and ensure it is fully seated and tightened. Use an appropriate thread weight and needle plate/foot suitable for heavy materials to avoid skipped stitches or damage. Test-stitch on a scrap piece of the same material and adjust tension and stitch length for smooth feed and even stitches before commencing the main work. Replace needles regularly if they become dull, bent or produce irregular stitching.

Использование и рекомендации

For best results, pair these leather needles with strong polyester or bonded threads and a walking foot or roller presser foot when sewing multiple layers or tough surfaces.
