How long: One month
A BIT late for last Christmas but plenty early for next, avoid gift disappointment and a creeping sense of resentment by requesting one of these from your nearest and dearest.
The Thread Detective will prevent the supercilious experts in your local fastener shop from ever getting the better of you again. What your other half’s 40 quid gets you is a number of thread identifiers hung on a wire lanyard. Each of these identifiers will tell you the size and pitch of a particular nut or bolt, or the threads on shock mounts and engine studs. Armed with this knowledge order at the fastener factor’s trade counter with confidence.
