Hex Bolts, 1/4 In.-20 X 6 In., A307 Grade A Zinc Plated Stee

Hi,

I am trying to find Grade 5 Bolts and I came across this one: (from Amazon, ships to my country)

Prime-Line 9058783 Hex Bolts, 1/4 In.-20 X 6 In., A307 Grade A Zinc Plated Steel (25 Pack)

 

Can anyone tell if this is harder to bend than the 60D timber ties or 60D penny nails?

(Don’t know if links are allowed, so I didn’t add the amazon link here)

Grade A307 is similar to grade 2.  Depends on the nails and bolts but usually easier and in some cases much easier to bend than a 60D.

A307 is substantively the same as a Grade 2 bolt, and id say it would usually fall between a timber tie and a 60d.

"What is the difference between A307 and Grade 2 fasteners? Both A307 and Grade 2 are commonly referred to as “low carbon” fasteners. A307 is an ASTM spec, while Grade 2 is an SAE spec (SAE J429). Functionally, A307 is typically supplied as a hex bolt, while Grade 2 is supplied is as hex cap screw (see below question to address the difference between the two). The overall strength ranges of A307 and Grade 2 overlap significantly, and they are often used interchangeably, even though they are technically different. A307 bolts are marked as such on the head, while Grade 2 screws are only required to display the mill head marking. In short, ASTM A307 is an “industrial” spec and SAE Grade 2 is an “automotive” spec." [source]

For bending purposes the two grades are close enough to still fall under the same category even if there a technical difference between them.

I feel like any G2s I had were easier than the timber ties... 60d galvs where harder than the timber ties... I've 60d brights from HD that are close to G5s... I injured myself a year ago bending and haven't' really done much since.

That all tracks with the numbers I have. Hope you've healed up stronger!
