You are confusing rebuttals of wildly innacurate claims by disciples of the "everything should be bolted with titanium" religion with commenting on specific manufacturers bolts with the aim of reducing their market share. Martin Robert´s bolts are the best titanium resin bolt available on the market

You know I'm just poking fun, right?

I definitely agree with your qualms about the Hely bolt. I don't understand why Fixe would produce a product like this when it's more expensive than perfectly suitable products already on the market.

Likely because they are offering a glue-in anchor product with improved corrosion resistant material (Duplex 2304) that compliments their (Duplex 2304) expansion anchor products.

Noting also that Petzl only offer a mechanical wedge bolt in a material other than 316 stainless (926/904L combo).

Was just researching Hely's and came upon this thread. Hely's take a 3/8" or 10mm hole. Every other glue-in I've heard of needs bigger. This seems worth noting...

so what you're saying is that it's the only practical glue-in option for places where power drills aren't allowed?

I (Bolt Products) make an 8mm resin bolt to be installed in a 3/8" hole.

Who makes the best 3/8" glue -in I wonder.

There are 2 glue-ins that take 3/8 hole? Bolt Products and Hely? others?

It's a clear advantage even for places where power drills are allowed.    

A 10mm (3/8") hole takes about half as much power to drill than a 14mm (9/16") hole.    If you need to drill 30-something holes a nasty hour's hike from the car, adding yet another battery pack (or two) to your 70lbs pack is brutal... but not as brutal as running out of power 1 or 2 bolts before finishing.

In addition to smaller hole to drill, what other benefits are there to using a 3/8" glue in?

Also, what are some of the disadvantages of using a 3/8" glue in, as opposed to the more common 1/2 or larger? Off the top of my head, I'm guessing that 3/8" is going to have more pressure and therefore rock deterioration in very soft rock types. As Jim has repeatedly made very clear, the smaller diameter doesn't really matter in terms of strength because it's already still far stronger than we need it to be. What else?

You reduce the bond area between the resin and the rock making good glueing more and more important.

Given the manufacturing method for Hely glue-in anchors it's surprising they did n't (apparently) consider an inference fit for inverse hole retention. They certainly won't stay inverted without duct tape!

Guideline #1: Don't be a jerk.
