Unique-Bargains M3 x 20mm Alloy Steel Hex Socket Grub Screws 50pcs

M3 x 20mm alloy steel grub screws

This pack supplies 50 headless set screws machined from alloy steel with a cup point and a 1.5mm hex socket. The M3 thread uses a 0.5mm pitch and the overall length is 20mm. They are graded 12.9 for high tensile strength and come in a black finish. The hardware suits assembly tasks in electronics, equipment and machinery where a flush, low-profile fastener is required.

50-piece bulk pack for production use

The quantity covers small-batch builds or maintenance stocks without needing multiple small boxes. A tolerance of ±2% means the actual count may vary slightly around the nominal 50 pieces. No batteries or additional components are included, so the pack delivers only the fasteners themselves. Buyers who need a different thread size, length or drive type will have to source a separate kit.
