Which is the right screws to use to mount ikea pegboard to studs for heavy weights with noob skills

pegboardstuds

I am super confused and overwhelmed with the amount of research I have done so pardon the post that may seem like a duplicate but I need help in specifically this context.

Problem Statement : I want to mount ikea pegboard 30"x22" onto studs. I used a stud finder to determine that my studs are 24" apart. The house is less than 4 months old so I am confused why they didn't follow the 16" standard.

The pegboard of 30"x22" comes with a bar that has holes at 23-5/8". Hence, I think I can mount it directly to the studs. I am making this for mountaineering gear so I want it to be super sturdy and hold good amount of weight.

Screw length :
I saw 3 inches being recommended most often so I was going to go with 3-1/2" screws just for safety. Is this okay? I just have regular drywall.

I shortlisted :

  1. Structural Screws
    All forums kept recommending this and I felt that it applies to my use case. But when I search structural screws on home depot they are not very cheap or many models. Everything is 5lb pack but I only need maybe 10 of those.
    This looks strong, is affordable. The top shaft looks unusual, Am I going to need anything special to drive this in? https://www.homedepot.com/p/Simpson-Strong-Tie-3-in-Strong-Drive-SDS-Structural-Wood-Screws-25-Pack-SDS25300-R25/203302236

This looks strong and easily drivable but is expensive. Is it worth the price. https://www.homedepot.com/p/GRK-Fasteners-5-16-in-x-3-1-8-in-Rugged-Structural-Screw-45-Piece-Pack-112221/203533461

  1. Cabinet screws

SPAX cabinet screw seems expensive : https://www.homedepot.com/p/SPAX-10-x-2-1-2-in-T-Star-Drive-Washer-Wafer-Head-Partial-Thread-Yellow-Zinc-Coated-Cabinet-Screw-75-per-Box-4281020050606/206870578

Generic cabinet screw is cheaper but is it going to compromise the strength value. https://www.homedepot.com/p/10-x-3-in-Zinc-Plated-Truss-Head-Phillips-Drive-Cabinet-Screw-25-Pieces-803002/204275480

  1. lagbolts : strong but overkill for my project. Harder for a noob like me because of predrilling need

Best Answer

There are a lot of different wood screws that would work for this application. However, I'm partial to Timberlok only because I've used them so many times in this type of application and they've never failed me. They are pricey but you can buy them in small quantities. One of the pluses I like is no predrilling is required and the shear strength is amazing for the diameter of the fastener.
