Overview

Minerallac 55853 is a 1/2-13 x 3-1/4" Grade 5 hex head cap screw with partial threading, zinc plated finish, and box packaging. Manufactured by Minerallac under the Cully sub-brand, this bolt is made from medium carbon steel, quenched and tempered for enhanced strength and durability. The three hash marks on the head indicate Grade 5 classification, meeting ASTM A449 standards for high-strength fasteners. Key specifications include a 3/4" head width, 5/16" head height, and coarse thread type. The zinc plating provides corrosion resistance for outdoor and industrial environments. This partial-threaded design reduces weight and material cost while maintaining full load-bearing capacity in the threaded section. Typical applications include heavy-duty machinery assembly, structural connections in construction, electrical panel mounting, and equipment fabrication where reliable, high-strength fasteners are required. The 3-1/4" length provides sufficient grip in thick materials while the hex head allows for secure wrenching with standard tools. Compliance with RoHS standards ensures environmental safety. Sold in boxes of 50 units for efficient inventory management. Contact Minerallac at 800-927-3293 or visit www.minerallac.com for technical support and bulk pricing.
