Becoming the car owner, each of us tries to protect in all ways known to it the child from encroachments. If "internal" is anyway protected from undesirable influence from possible offenders, everything that is outside, is subject not only to winds, but also "careful" hands of "professionals".
If you decided to buy a set from four bolts ("sekretok") and a key adapter, we advise to you not to hurry up. Having walked only on one automobile market, we counted 12 versions of such sets. The prices for them fluctuate depending on a material of which they are made, and originality of a design.
There are the obvious consumer goods representing a bolt clown with the same key. The bolt with big height of an eccentric head has no protection against twisting by an alligator wrench. This option can interest owners of those cars on whom there are cast disks with a deep seat under "sekretka". The price of such protection – from 3 to 5 c.u.
Bolts with being scrolled a protective ring and everything with the same clown stand to $10. But the ring publishes unpleasant sounds when driving, making impression that to the car adhered a rope with cans. Many get rid of this noise, having tightened up under the bolt basis a simple elastic band from hair curlers.
Having reached the price in 15 c.u., confidential bolts start to remind any more "ugly ducklings" which заморились to rust on a counter open-air, and white swans, is proud lifting the steel head over a heap of everyones шайбочек, гаечек, small screws, прокладочек, lying right there. As a rule, these "sekretka" differ the high workmanship, the corresponding heat treatment and sheeting existence.
Too there is a lot of design options. All of them, as a rule, with the protective ring fixed on a bolt through a rubber sealant, relieving of extraneous noise. Have any more one, and two keys (one spare). Forms of "secrets" are rather various. Beginning from the simplest, but already improved clowns, before intricate shlitsevy connections: these as it seems to us, the most reliable and convenient at installation.
Those treat the last class, which cost – from 15 to 25 c.u. These copies as though descended from cloths of avant-gardists. Here to you both "trekhlistnik", and nuts of the wrong form, both the truncated cone, and bolts with the turnkey openings, reminding a sign "At a wheel – the deaf". All of them are made with a protective ring. Is very convenient and practical, but come across and raising doubts in the suitability to work.
Buying "sekretka" from us in the city, you, as a rule, are not insured from that the same key is not present and at the malefactor. The matter is that producers will change hardly the sizes of bolts and keys to them, providing identity of each set. Therefore, if to put "sekretka", acquired in other city. Or to order specially in the familiar turner. In this case the probability of that your wheel will get to the neighbor in parking, already less, but...
And still sense to establish sekretka is – from among potential applicants for your wheels technically unsophisticated boys are excluded, "unauthorized" removal of wheels needs an extra time in summary careless manipuliyatsiya of competent malefactors the alarm system established by the car can manage to work. If, of course, malefactors are not rather competent, that it to "neutralize".
Let's not press in technical details, tempting thus "irresponsible". Let's tell only that if owners of light-alloy wheels with the deepenings hiding heads of bolts, can "sleep easily" in the presence of one "sekretka" on a wheel, steel disks it is meaningful to fix three-four "cunning" bolts (or nuts), it is desirable different that is rather expensive and troublesome. However, the healthy sleep is more expensive.
