Holo-Krome 436.1RL-2 is a precision-manufactured socket head cap screw produced by Holo-Krome, a trusted American manufacturer of critical-application fasteners since 1929. Holo-Krome socket head cap screws are engineered for demanding applications requiring high strength, precise tolerances, and reliable clamping force.

Key Features:

• Thermo-Forged® Construction: Cold-heading process preserves continuous, uncut metal grain fibers for superior fatigue resistance compared to machined alternatives
• Heat-Treated Alloy Steel: Provides high tensile strength suitable for critical fastening applications
• Class 3A Thread Fit: Meets ASME/ANSI B18.3 and ASTM A574 standards for precision thread uniformity and accuracy
• Controlled Radius Roots: Holo-Krome's proprietary radius root thread form reduces stress concentration at thread roots
• Tru-Ground® Bearing Surface: Precision-ground head and shoulder surfaces deliver unequalled concentricity between head and body
• Made in USA: Manufactured at Holo-Krome's Wallingford, CT facility

Holo-Krome socket head cap screws are the preferred choice for machine builders, toolmakers, and engineers who require consistent performance in high-load, tight-tolerance assemblies. Each fastener carries full traceability back to the source steel mill.
