Threaded Studs Add Versatility to Bonafide EX123 Replacing the thumbscrews that come with the dashboard of a Bonafide EX123 with the YakAttack 1.5" 1/4-20 Threaded Studs allows me to add YakAttack accessories that use YakAttack Lock'N'Load mounting system. In the photo you see a YakAttack Omega rod holder on the left and on the right side a YakAttack Zooka II rod holder being used to deploy a stake-out pole through the O-ring of my anchor trolley. The second picture shows the stake-out pole deployed on the river to hold my position.
