The Rolson O-ring, washer and cable tie assortments on this page exist to solve one specific and very annoying problem, which is a five minute job halting because you do not own one washer in one size. Each assortment arrives graded by size in a compartmented box, so the part you need is already in the house and already sorted. Everything here is genuine Rolson Tools stock, held in the UK and dispatched with tracked delivery. As DIY assortment boxes go, these are the graded, labelled kind rather than a loose bag of mixed parts.

Sealing and fastening assortments

The 225 piece O-ring assortment is the one that pays for itself first, since a dripping tap, a leaking hose connector or a weeping shower fitting is almost always a perished O-ring rather than a failed valve. The 720 piece washer assortment covers the flat and spring washers that stop bolted joints working loose, and the 300 piece E clip assortment and 150 piece spring assortment cover the small retaining parts that go missing during a repair. The 80 piece hook and eye bolt assortment handles gates, sheds and light hanging work.

Cable management and electrical assortments

Four assortments cover wiring and cable work. The 150 piece cable tie pack and the 390 piece cable clip assortment tidy runs of speaker, network, alarm and lighting cable, while the 127 piece heat shrink wrap assortment insulates and strain relieves joints properly instead of relying on tape. The 50 piece hook and loop set handles removable bundling for anything you expect to unplug again. These pair naturally with our fixings and adhesives and lighting and electrical ranges.

Storage, totes and building a spares drawer

The 1000 piece assortment tote and the 2 piece 335 x 260mm stackable organiser handle the storage side, and the 200 piece spare eyelet pack and 50 piece PZ2 x 25mm bit pack cover consumables that wear out. The sensible approach is to buy one assortment per problem area, label the box lid and keep it in the same drawer, so the next repair starts with the part in your hand. Browse the wider Rolson Tools, general tools, DIY essentials and tool bags and belts ranges to build the kit around them.

Which assortment to buy first

If you are starting a spares drawer from nothing, buy in the order that things actually fail in a UK home. O-rings come first, because taps, showers and hose connectors weep far more often than anything else and the fix takes minutes once you own the ring. Washers come second, since they are needed on almost every bolted repair and are the part people most often find themselves one short of. Cable ties and clips come third, because cable tidying is the job everyone postpones and then does all at once. Heat shrink, springs and E clips are worth having before you need them rather than after, since these are precisely the parts no local shop stocks in the size you want on a Sunday afternoon.
