Hillman Zinc-Plated Steel Fine Thread Slotted Hex Nuts 5/8-18, 6 Pack

About this item

• LOCKS WITH A COTTER PIN: This slotted hex nut is locked positively with a cotter pin, so it physically cannot back off under vibration, making it the safe choice for axles, shafts, and rotating parts where a nut must never come loose.
• SLOTTED CROWN, HEX FLATS: Fitting a 5/8-18 fine-thread bolt, slots cut across the crown line up with the cross-hole in a drilled bolt or axle, so a cotter pin drops through both and pins the nut, while the six flats take a wrench to set it.
• ZINC-PLATED STEEL: Made from steel with a protective zinc plating, the nut resists rust and corrosion for dependable indoor and outdoor use, keeping clean threads and a positive cotter-pin lock on axles and machinery over time.
• AXLE AND MACHINERY USE: Ideal for wheel axles, spindles, shafts, tie rods, and rotating machinery where a positive mechanical lock is essential, a dependable choice for automotive, trailer, and equipment repair and assembly.
• TRUSTED HILLMAN QUALITY: Hillman supplies dependable fasteners and hardware that homeowners and pros rely on for everyday projects. Keep these nuts on hand for assembly, mounting, and repair jobs around the home and shop.
