Narva Heavy Duty Cable Ties 9mm x 530mm - 100Pc This nylon tie is UL approved, with a UL94V-2 flammability rating and meets or exceeds tensile strength MIL-S 23190E with an operating temperature of -40oC to 85oC. The 2 basics that should be kept within arms reach whether in the workshop or home are usually duct tape and WD40. Saying that, you really should add a third to that list and always have a selection of cable ties close at hand. Whether tidying up that mess of cables down the back of the tv cabinet or re-attaching front bumpers after getting a little to close to the gutter at the supermarket you'll be surprised at the versatility that the humble black cable tie provides in all manner of circumstances. With the most common construction of cable ties being nylon they have a tremendous amount of holding strength for something so thin or small. Whether holding wiring and coolant plumbing out of the way whilst doing an engine swap through to stringing up a tarp for some extra shade or cover whilst camping you can't fault how much time and grief they save when you have a bundle handy. So do yourself a favour and pick up an extra pack or two when you are replenishing your workshop consumables next. They are certainly one of those items that you can never have too many of and it never hurts to have a pack slung in the glovebox or boot for those unexpected mishaps that happen on the road.
