Whenever any type of lifting sling is to be used for rigging-up a load, whether it be a nylon or polyester sling, or a chain or wire rope sling, the sling should always be inspected for damage and removed from service if there is any doubt about its capacity to sustain the lift. At the Risk Tool Box, we recommend that a systematic approach to sling inspections be adopted, and the checklist below can be used to audit and verify that inspections are being done as part of a rigging procedure.
For further information about our approach to procedure development and audit checklists against procedures, feel free to get in touch.
Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag. Import charges previously quoted are subject to change if you increase you maximum bid amount. Use plenty of lubricant - WD40 works well for aluminum and brass, high sulfur pipe threading oil works well for steel. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable.

Back the tap up a quarter turn every half turn or so to break the chip and you'll have less chance of breaking a tap.
Metric taps are easier, because the pitch given is already one pitch, rather than threads-per-inch, like SAE threads. As previously mentioned, you can go a little bigger in hard-to-tap materials, unless it's something critical. There are various goopy tapping fluids on the market that really improve results, but even a few drops of oil is a big improvement.
