For want of an M8 x 30mm bolt . . .

It still amazes me how well I can prepare for a long, remote journey, yet still find myself unprepared.

Over the course of four trips to Australia in the Land Cruiser Troopy we bought there, I slowly accumulated a pretty decent selection of tools, highlighted by a superb Bahco S106 combination kit (see here), which includes full 1/4 and 1/2-inch socket sets, wrenches, plus numerous drive fittings. An additional set of 1/2-inch deep sockets, a screwdriver selection, an electrical tester, and various pliers rounds out the kit. 

Our recent trip was without doubt the hardest on both our Troopy and that belonging to Graham Jackson and Connie Rodman, as we covered 2,600 kilometers of dirt tracks between Coober Pedy to Perth, some of them heavily corrugated. And as on earlier trips, substandard work done by a mechanic in Sydney (not the Expedition Centre which did all the camper conversions, but a repair shop nearby) began to manifest itself. A new radiator installed on Graham’s vehicle, bought long distance before we arrived—and guaranteed by the mechanic to be “as good as Toyota”—began leaking halfway through the journey. Radiator stop-leak controlled but did not completely plug it. Next, I found the transfer case lever in our vehicle would engage four wheel drive but flopped back and forth rather than engage low range. The nut on that section of linkage had fallen off. (The transmission had been removed to repair a leak before a previous trip.)

A bit farther on, Roseann and I started noticing a rattle that seemed to be coming from the exhaust, as if some gravel had become caught on top of a heat shield. But soon we could hear an obvious exhaust leak. Underneath the vehicle I inspected the “performance” exhaust system the mechanic had installed. A joint near the middle was completely loose. It had been connected with two bolts and nuts—no flat washers, no lock washers, no jam or nylock nut, no Loctite. One bolt and nut was completely gone; the other I easily removed with my fingers, to find most of the thread stripped.

And that was a problem, because while I had plenty of tools with which to install or remove virtually any nut or bolt on the truck, I had not gotten around to the item on my pre-trip list that read BUY SPARE BOLTS AND NUTS.

Sigh . . .

This time I got lucky. We had some leftover washers from a RAM mount, plus several bolts I had bought to secure it, and against all odds they just happened to be a suitable size and length. We were soon back on the road with a quiet exhaust (and Graham had found an extra M8 nut with which to fix the low-range linkage). 

Needless to say, when we got to Perth I made my first task a trip to the local Bunnings to get a start on rectifying the situation before we loaded the Land Cruisers into a container for Africa.

One suggestion: I usually buy mostly high-tensile spare bolts (Grade 8 in SAE or 8.8 or 10.9 in metric), figuring that it won't hurt to replace a missing standard bolt with a high-tensile spare, and I can be assured of having the proper strength fastener for a critical component.

The Hiplok Z Lok

Securing one’s possessions while on a trip is an annoying but critical concern. Inside the vehicle we lock down our large, important items—Pelican cases, etc.—with bicycle-style cables and padlocks stout enough to resist all but a really determined criminal with bolt-cutters and time. 

But there are many other smaller items, and other circumstances, where one needs minimal protection from a snatch-and-run thief, involving minimal hassle and weight. Some time ago I read about the Z Lok from Hiplok, and my bicycling friend Geoff in Sydney just gave me one.

The Z Lok is essentially a glorified ziptie, but much stouter, cored with a strip of steel—and, saliently, reusable. A simple forked key disengages the double steel teeth that secure the tie inside a steel-reinforced head. It’s strong enough to resist a really strong yank, and would be nearly impossible to cut with a knife (although not with a good pair of side cutters).

While any thief could buy one and carry the forked key around looking for an opportunity, that’s an unlikely scenario. The Z Lok would be excellent for many situations—locking my camera case to the table while I’m having lunch at an outdoor café; securing my bicycle helmet to the bike—even quickly locking the bike itself if I just wanted to duck inside a coffee shop for a takeaway.

At around 12 bucks on Amazon, or $20 for a pair, I can think of a zillion uses for these things.
