Caster plate mounting hardware — carriage bolts, slotted hex bolts, lock nuts, and washers for installing plate-mount casters. Standard 3/8-16 and 1/2-13 sizes covering the most common caster plate bolt patterns. Bulk packs for fleet installations and OEM use. Stocked at our Mansfield, TX facility.
Plate casters need 4 bolts per caster — typically 3/8-16 or 1/2-13. Carriage bolts have a square shoulder that prevents the bolt from spinning during installation. Slotted hex bolts allow tightening from below.
3/8-16 most common on light-medium casters. 1/2-13 on heavy-duty.
Bolt length = plate thickness + equipment material thickness + 1/4 inch. Too short and the bolt won't engage; too long and threads stick out.
Carriage: square shoulder prevents spin. Slotted: tighten from below with a slotted screwdriver.
Caster mounting bolts vibrate loose under use. Use nylon-insert lock nuts or thread locker to prevent loosening.
