Product Description

Product Description

Hexagon Head Flat End Set Screws

These precision fasteners combine superior mechanical properties with enhanced corrosion resistance through specialized surface treatment. Manufactured from alloy steels (SCM435/40Cr) and heat-treated to achieve 10.9/12.9 grades, they deliver tensile strengths of 1000-1200MPa. The black oxide coating  provides:

Minimal dimensional change (3-5μm coating thickness) for precise interference fits
Improved wear resistance compared to untreated surfaces
Basic corrosion protection (supplemented by oil retention)
Key Applications:
• High-load industrial equipment requiring positional stability
• Precision machinery where reflective surfaces must be avoided
• Automotive transmissions and aerospace assemblies

Standards Compliance:

DIN 913/914 (Metric)
ANSI B18.3 (Imperial)
RoHS & REACH certified

Packing & Delivery

Bulk/Fiber Bag/Neutral packing

Carton/Box

Wood Pallet/Box

Bagged packaging is ideal for smaller quantities of fasteners. The fasteners are placed in durable plastic bags, which are then sealed to protect the contents from moisture and dust. Each bag is clearly labeled with product details and quantities. This packaging is easy to handle and transport for smaller orders, making it convenient for workshops and retail settings.

Boxed packaging offers a more structured solution for medium to large quantities of fasteners. The fasteners are packed in sturdy cardboard boxes, which provide additional protection against physical damage during transit. The boxes are designed to stack neatly, optimizing storage space. Each box is labeled with essential information, ensuring easy identification and inventory 

Palletized packaging is used for bulk shipments of fasteners. Multiple boxes or bags are securely strapped onto a pallet, creating a stable and easily transportable unit. This method is highly efficient for large-scale distribution and warehousing. Palletized packaging ensures that large quantities of fasteners can be moved quickly and safely using forklifts, reducing handling time and labor costs.
