Countersunk Washer Blk 1/4in x 1-1/4in 10pk

The Countersunk Washer Blk 1/4in x 1-1/4in 10pk by Allstar Performance is an essential fastener kit for marine assembly, transom reinforcement, and structural boat repairs. Anyone who has spent time on the water knows that fasteners endure constant vibration, saltwater exposure, and mechanical stress—this 10-pack addresses those demands with a proven solution. Whether you're securing through-hull fittings, reinforcing mounting brackets, or assembling custom rigging systems, countersunk washers distribute load evenly and sit flush with deck hardware, creating a clean, professional finish that resists corrosion and maintains watertight integrity.

These countersunk washers feature a 1/4-inch diameter hole and 1-1/4-inch outer diameter, sized to pair with 1/4-inch bolts and studs in marine applications. The black finish provides corrosion resistance and eliminates light reflection that can interfere with deck visibility. The countersunk profile allows the washer to sit flush beneath fastener heads, preventing trip hazards and reducing snag points on rigging or gear. Each washer is engineered to maintain a secure grip under dynamic loads—critical for systems experiencing constant engine vibration or wave action, where ordinary flat washers would gradually loosen and compromise structural alignment.

This 10-pack suits both freshwater and saltwater boaters who need reliable fastening hardware for routine maintenance, upgrades, or emergency repairs. Experienced anglers and recreational boaters routinely keep backup fastener kits on board for securing rod holders, replacing corroded hardware, and reinforcing console mounts. The black finish integrates seamlessly with modern marine hardware and Allstar Performance's reputation ensures consistent quality across the set. Stock multiple packs for large projects, transom rebuilds, or as part of your boat's emergency repair locker.
