1.5 Red Screwdriver for Overlock Sewing Machine

This 1.5mm hex screwdriver with a red handle is the standard size tailors and technicians use to adjust the needle clamp screw on industrial overlock (interlock) sewing machines across brands like Juki, Yamato, Pegasus, Siruba and Kansai. Best for tailoring units, garment factories and home-based overlock users who need the correct hex size to change needles without stripping the tiny screw head.

• 1.5mm hex tip sized for standard overlock needle clamp screws
• Red handle colour-codes this as the 1.5mm size, matching the convention most machine tool kits use
• Comfortable grip for repeated needle changes during a shift
• Compact length fits into the tight needle bar area of an overlock head
• Hardened tip resists rounding off on tightly fitted screws

Use Cases

• Changing needles on an overlock machine during routine production
• Keeping a correctly sized spare on hand since this is the screwdriver most often misplaced on the factory floor
• Adjusting other 1.5mm hex screws on the machine head, such as small guide or clamp fittings

Benefits

• Correct hex size prevents the rounded, stripped screw heads that come from using a slightly wrong-sized driver
• Colour-coded handle lets an operator grab the right size instantly without checking each time
• Inexpensive enough to keep multiples at every machine station

How To Use This Screwdriver

1. First, switch off the machine and raise the needle bar to its highest position.
2. Next, locate the needle clamp screw on the side of the needle bar.
3. Then, insert the 1.5mm hex tip fully into the screw head before turning.
4. After that, turn counter-clockwise to loosen and remove the old needle.
5. Following this, insert the new needle to the correct depth and hold it in place.
6. Finally, tighten the clamp screw snugly — avoid overtightening, which can crack the clamp over time.

Frequently Asked Questions

Why does the screwdriver size matter for needle changes?

Needle clamp screws are small and soft compared to general hardware screws. A screwdriver even slightly smaller or larger than 1.5mm tends to slip and round off the screw head, which then needs to be drilled out — a much bigger repair than the original needle change.

Is red always the 1.5mm size?

Most industrial sewing tool kits use red for 1.5mm as a common convention, but this isn’t a universal standard across every brand. If you’re buying a replacement for a specific kit, it’s worth checking the tip size marked on the old screwdriver rather than relying on colour alone.

Will this fit my lockstitch machine’s needle clamp too?

Many single-needle lockstitch machines use a different hex or slotted screw size than overlock machines. Check your existing screwdriver or the screw head before assuming this 1.5mm hex will fit.

How often do factories replace these screwdrivers?

They’re one of the most frequently lost small tools on a production floor, so factories running several overlock machines typically keep a handful of spares rather than one per line — replacing a ₹20 screwdriver is far cheaper than machine downtime while someone looks for the one that’s missing.

Does this ship with COD and pan-India delivery?

Yes, this screwdriver ships pan-India with cash-on-delivery available on eligible orders, along with GST billing for business buyers.
