Description
Overview:
Metric Spring Roll Pins are slotted tubular fasteners made from hardened spring steel for dependable location and locking of components. This assorted mini box contains 160 pieces covering common metric sizes, including 2.5 mm, 3 mm, 4 mm, 5 mm diameters, plus 6 x 40 mm, 8 x 24 mm, and 8 x 55 mm. The split design compresses as the pin is driven into a correctly sized hole, creating a secure interference fit that resists vibration and shear forces. Suitable for machinery assembly, automotive repairs, plant, agricultural kit, and garden equipment such as lawnmowers and compactors, these pins help align parts, retain shafts, and secure levers, gears, pulleys, and guards. Packed in a compact box for tidy storage in the van, site box, or workshop.
