3/8" Side Post Battery Terminal Bolt, Standard Battery Side Post Extender Stud Compatible with GM Post, 2 Different Lengths (2 Pairs W/ 2 Spacer)

The thread is 3/8 inch-16, the single measurement this listing commits to. Four bolts arrive in two lengths, a short pair and a long pair, and the supplier's instruction is to fit whichever pair suits and keep the other; the two spacers in the packet belong with the long bolts.

Two lengths, and no figure for either

The whole selling point is that you get a choice of reach, and neither reach is quantified. Short and long: that is the extent of it, with no millimetres and no inches attached to either pair. Whether the short bolt clears your cable lug, or the long one reaches far enough out of the post to be worth having, cannot be answered from what is printed. On an extender that is not a detail, it is the question, and it needs to go to the seller before you order.

Plated iron, and what is not claimed for the plating

The metal is zinc plated iron and the supplier says so plainly, which is more than some listings manage. What follows it is nothing: no statement about how the finish behaves at a battery terminal, no salt-spray figure, no service life. Nor is there a tightening torque for a stud that winds into the post itself. We will not invent either figure on the supplier's behalf, so both are worth raising if this bolt is going somewhere awkward to reach twice.

Key features

• Zinc plated iron: the material is named outright in the supplier's opening line.
• 3/8 inch-16 stud thread: quoted with its pitch, and repeated with the pitch intact.
• A short pair and a long pair: four bolts covering two reaches, with one pair meant to be used.
• Two spacers: supplied for the long bolts specifically, not for the short ones.
• GM post compatibility: named as suiting GM battery post adapters.
• Cable straight onto the battery: sold for hooking wire directly to the battery through the extended stud.
• Direct fit replacement: the supplier's phrase for how it goes in, with nothing to modify.

Unanswered by this description

• Neither length is quantified. Short and long are the supplier's only words for them, and a bolt sold on reach with no reach printed cannot be checked against your terminal.
• No tightening torque is given, on a threaded fastener that goes into a battery post.
• No current rating and no voltage rating appears, though the stud sits in the starter path by design.
• Nothing is claimed about how the zinc plating holds up in service. There is no corrosion wording here at all, in either direction.
• A brand name has been cut out of the supplier's second fitment sentence, leaving it ungrammatical and the battery it referred to unnamed. We have not guessed at it.
• One pair is fitted and one pair is left over, which the supplier states. The description sets out no numbered fitting procedure.

A set of GM-pattern extender studs whose thread is fully specified and whose lengths are not specified at all, which is the trade you are making.
