About this file
This document is a product specification and certification package for heavy hex fasteners manufactured by LEP Special Fasteners, Inc.
The October 30, 2008 certification letter from LEP Special Fasteners confirms that all components are manufactured domestically at the company's Frankfort, Indiana facility and comply with DFARS requirements. The company manufactures private label Grade 9 cap screws and standard Grade 5 and Grade 8 cap screws, utilizing only domestic steel mills to ensure raw material consistency prior to cold heading. The document includes comprehensive technical specifications for heavy hex nuts compliant with ASME B 18.2.2 and 18.2.6 standards, covering nominal sizes from 1/4 inch to 1 inch with detailed dimensional data for width across flats (F), width across corners (G), and thickness (H). Material specifications include Grade C, A194 Grade-2H, A 563 Grade-DH, and A 563 Grade-DH3 designations with corresponding chemical composition requirements and hardness standards. Additional specification sheets detail heavy hex bolts conforming to ASTM A193 Grade B7 and ASTM A307 Grades A and B, providing dimensional tables, tolerance information, and mechanical properties including tensile strength and elongation requirements. The documentation establishes that products meet federal procurement standards for domestic manufacturing and material sourcing compliance.
