Each nut is machined from solid steel and zinc-plated for rust protection, making them suited to the wet, corrosive conditions boat trailers see on a regular basis. They are designed to thread onto roller shaft ends, retaining the roller in place on the bracket while resisting the elements that cause bare steel hardware to corrode and seize over time.\u003c\/p\u003e\u003cp\u003eThis is a straightforward hardware replacement item: if the cap nuts on a trailer roller assembly have rusted, rounded off, or gone missing, this 4-pack provides a direct, ready-to-install fix without needing to replace the entire roller bracket. The zinc plating gives the nuts a silver finish and adds a layer of protection against saltwater and freshwater exposure alike. Each pack contains 4 individual cap nuts, sized for 5\/8 inch shafts, so buyers should confirm their roller shaft diameter before ordering.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Tie Down Engineering\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 86310\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Cap Nut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 5\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack Quantity:\u003c\/strong\u003e 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Alloy Steel, Zinc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Zinc-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Silver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.11 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 081628863109\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Trailer Rollers \/ Shafts hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits 5\/8 inch trailer roller shafts.
