Countersunk Bolt Kit Fluorescent Yellow 50pk

The ALLSTAR PERFORMANCE Countersunk Bolt Kit Fluorescent Yellow 50-pack (ALL18688-50) is a complete fastener assembly purpose-built for securing body panels, guards, and trim components on high-performance machines and vehicles. This 50-piece kit contains 1/4-20 thread countersunk bolts at 1 inch in length, paired with countersunk washers and lock nuts—all finished in fluorescent yellow with zinc oxide plating for corrosion resistance and high visibility in workshop and field environments.

Each bolt features an Allen head (hex socket) design for tool-consistent torque application without cam-out risk. The 1/4-20 thread pitch is a common metric in automotive and powersports fastening, offering sufficient clamp load for body and cosmetic work while remaining easy to source replacements. The countersunk profile allows bolts to sit flush with panel surfaces, eliminating snag points and maintaining clean aesthetics on exterior trim. Steel construction with zinc oxide coating provides adequate corrosion protection for indoor storage and moderate outdoor exposure; for salt-air or marine environments, stainless upgrades are recommended. The fluorescent yellow finish aids visibility during assembly and inventory management, reducing the risk of lost fasteners on the shop floor or job site.

This kit serves fabricators, restoration shops, race teams, and off-road builders who need reliable body fasteners in volume. The 50-count supply reduces trips to the bin and supports mid-sized panel work or repair jobs without excessive overstocking. Matching lock nuts prevent vibration-induced loosening—critical on vehicles subject to engine harmonics, rough terrain, or high-speed operation. Operators familiar with aftermarket fastener kits will recognize ALLSTAR PERFORMANCE's positioning as a value-oriented supplier for automotive enthusiasts and professional shops.
