H/T Special Washers - 5/16in .590in OD (100)

The H/T Special Washers - 5/16in .590in OD (100) from B and B Performance Products are essential fastening components for marine engine builds, outboard rigging, and high-performance boating applications. These precision washers distribute load evenly across bolt heads and surface areas, preventing dimpling, crushing, or corrosion damage to aluminum, fiberglass, and composite marine components. If you've spent years on the water, you know that the right washer protects your investment—especially in saltwater environments where fastener failure can mean a breakdown far from shore.

With a 5/16-inch bolt hole diameter and .590-inch outer diameter, these H/T Special Washers are sized for mid-range fastener applications common in marine engine mounting, transom brackets, and control cable hardware. The larger outer diameter (OD) relative to the bore creates a wider bearing surface, critical when securing components to softer materials like wood stringers or gelcoat hulls where concentrated pressure can cause structural damage. This 100-count bulk pack means you'll have spares on hand—a practical advantage when servicing your rig or building a custom application without multiple reorders.

Marine mechanics, boat builders, and serious anglers rely on B and B Performance Products washers for outboard motor rebuilds, transom reinforcement, and custom rigging. Whether you're upgrading hardware on a center console, reinforcing a fishing platform, or assembling a high-horsepower engine package, the H/T Special Washers provide the load-spreading foundation every critical fastener deserves. Stock a box in your marine locker and eliminate mid-season fastener failures that could compromise safety or leave you stranded.
