ZELCAN 400-Piece Metric Spring Pin Kit, M1.5–M6 Carbon Steel

Made from 45# carbon steel with a black oxide finish, this ZELCAN kit brings together 400 slotted metric spring pins for fastening and repair work.

It covers seven diameters, from M1.5 to M6, with assorted lengths from 6 mm to 30 mm. That range helps when different assemblies call for different pin sizes.

For a single, known repair, buying one specific pin size may be enough. This assortment is a practical fit for keeping several metric options ready for fixture, appliance or vehicle repairs.

What matters most

Each pin is a slotted steel roll pin that expands against the sides of its intended hole. Chamfered ends help guide it into place, while the split design provides a firm fit when the diameter is matched to the hole. The black oxide finish is intended to support corrosion resistance, and the pins’ compact form suits applications where space around the joint is limited.

The set contains 40 M1.5 pins, 30 M2, 60 M2.5, 90 M3, 120 M4, 30 M5 and 30 M6 pins. Lengths vary from 6 mm to 30 mm. A labelled plastic storage case keeps the assortment organized, making it easier to find a size during a repair or return pins to their place afterward.

Buyer feedback highlights the range of sizes and the usefulness of having an assortment on hand. Opinions are mixed on sizing and reliability, so matching the selected pin to the requirements of the joint is an important part of choosing the right one.

Everyday use

Keep the case with general repair supplies for work on fixtures, appliances, machinery or vehicles. When replacing a pin, identify the required diameter and length for the joint, then select the corresponding size from the case. The assortment is especially useful when maintaining several items that use different metric pin sizes, rather than stocking only one size for a single task.

The steel construction and black oxide finish make this a purpose-built hardware assortment for fastening applications. Store the pins in their labelled case between jobs to keep the different sizes together and accessible.

Practical tips

Before installation, match the pin diameter to the intended hole and choose a length suited to the joint. The pin is designed to be slightly larger in diameter than its intended hole so it can expand and hold in place. Align it carefully as you fit it, the chamfered ends help with insertion. Keeping the assortment organized by size also makes it simpler to identify a replacement for a removed pin.
