Manufactured from Grade 2 steel with a hot-dipped galvanized finish, this bolt measures 5.5 inches in length under the head and features partial threading along the shank. It meets ASTM A307 standards, making it appropriate for low-carbon steel bolting used in structural connections. Licensed trades and construction contractors install this fastener type in framing, equipment mounting, and infrastructure assembly where corrosion resistance is required and a bearing-length shank is preferred over full threading.\u003c\/p\u003e\n\u003cp\u003eThis hex head bolt is suited for both residential and light commercial construction and mechanical applications where UNC thread engagement and a galvanized finish are specified. The hot-dipped galvanized coating provides enhanced corrosion protection compared to electroplated alternatives, making it a reliable choice for outdoor, wet, or treated-lumber environments. Partial threading allows for a smooth shank section that bears shear load more effectively in clearance-hole applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC thread size with partial threading for shear-bearing shank applications\u003c\/li\u003e\n  \u003cli\u003e5.5-inch length under head for deep fastening depth in structural assemblies\u003c\/li\u003e\n  \u003cli\u003eHot-dipped galvanized finish for superior corrosion resistance in outdoor and treated-lumber environments\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction meeting ASTM A307 fastener standards\u003c\/li\u003e\n  \u003cli\u003eInch measurement system with UNC thread standard for compatibility with standard SAE hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/8-11 UNC hex head bolt for use with any application or assembly specifying ASTM A307 Grade 2 galvanized hardware in the inch measurement system.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by carpenters, ironworkers, millwrights, or other licensed tradespeople depending on the application. Always confirm that the mating nut and washer are rated for the same grade and finish to avoid galvanic incompatibility.
