I am looking for Grade 8 sex bolts in a 1/2" to 5/8" diameter barrel with a grip range of 3" to 3-1/4".
Prefer to find a tapered seat style for a flush mount.
I can find them in 18-8 Stainless, but I would really like to have Grade 8.
Anyone know any sources for such fastener?

Anyone know any sources for such fastener? You might try your local bolt supplier and ask for A490 specs. Don't settle for A325.

These are what I can find in stainless steel.
However I would like to get them in just standard grade 8 steel.

Nope - you can't. I don't think you can harden stainless, even though it's already hard. No way stainless is grade 8. When you need grade 8, you need grade 8!

Nope - you can't. I don't think you can harden stainless, even though it's already hard. No way stainless is grade 8. When you need grade 8, you need grade 8! 17-4 Stainless is available and very comparable strength wise to typical grade 8, and far superior to typical grade 2 stainless fasteners. Physical Properties: Melting Point: 2560 - 2625°F (1404 – 1440°C) Density: 0.282 lbs/in3 / 7.8 g/cm3 Modulus of Elasticity in Tension: 28.5 X 106 psi / 197 GPa Mechanical Properties: Condition: Solution Treated (A) Tensile Strength Minimum (psi): 160,000 Yield Strength Minimum 0.2% offset (psi): 145,000 % Elongation in 2” Typical: 5% Hardness: Rockwell B85 Condition: Hardened + Aged (TH1050) Tensile Strength Typical (psi): 200,000 Yield Strength Typical 2% offset (psi): 185,000 % Elongation in 2": 8% Hardness: Rockwell C35 Condition: Aged (H1075) Tensile Strength Typical (psi): 175,000 Yield Strength Typical 2% offset (psi): 165,000 % Elongation in 2": 8% Hardness: Rockwell C37 Condition: Aged (H900) Tensile Strength Typical (psi): 210,000 Yield Strength Typical 2% offset (psi): 200,000 % Elongation in 2": 7% Hardness: Rockwell C45 For reference sake, its likely double the cost of typical SS.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

Sex bolts.......am I missing out on something here? Doc should know.... paging doc, paging doc And let’s not forget “mating screws”. Apparently there is a language of love that I never learned.

Irrelevant if no one makes sex bolts in 17-4 stainless.
