Parts Desk Insights
Best Use Case: A strong choice when you want an externally accessed, surface-mounted locking bolt that resists corrosion and can be installed for vertical or horizontal operation on doors, gates, and marine cabinetry.
Common Issues: If the bolt won’t lock reliably, double-check alignment between the mating surfaces and the closure so the notch/barrel engages correctly (especially in vertical installations). Since it’s countersunk for FH fasteners, confirm you’re using the correct FH fastener size/type—this bolt does not include fasteners.
