Jefferson 250 Piece Grub Screw Assortment Socket Set Screws

Details and Engineering Benefits of the Jefferson 250 Piece Grub Screw Set

• High-Tensile Alloy Steel: Delivers outstanding clamp load and shear strength, preventing fasteners from stripping or shearing under sustained rotational torque.
• Recessed Hex Socket Drive: Allows for precise tightening with standard Allen keys even in tight, recessed locations where spanners cannot reach.
• Cup Point Profile: Bites firmly into shafts and mating metal surfaces, providing high resistance to vibration and preventing components from slipping out of alignment.
• Corrosion-Resistant Black Oxide: Protects each fastener against rust, workshop fluids, and atmospheric moisture for long-lasting mechanical reliability.
• Comprehensive 250-Piece Metric Range: Supplies a practical selection of common metric thread sizes and lengths, ensuring the correct replacement is always ready on the bench.
