Product Description

Product Description

Hex Head Bolt

1. Design & Construction

Head: The six-sided shape allows for 60° tool engagement, maximizing torque transmission.
Thread: Available in coarse (UNC) or fine (UNF) pitches, with partial or full threading options.
Material Grades: Common grades include 4.8, 8.8, 10.9 (strength ratings per ISO 898-1), and A2/A4 stainless steel for harsh environments.
2. Performance Characteristics

Load Capacity: Rated by proof load (e.g., 8.8 grade: 600 MPa tensile strength).
Surface Treatments: Zinc plating, galvanization, or black oxide coating for corrosion protection.
3. Industrial Applications

Construction: Joining steel beams in bridges and buildings.
Automotive: Engine block assembly and chassis components.
Machinery: Secure fastening of heavy-duty equipment.
4. Installation Guidelines

Use a torque wrench to avoid over-tightening.
Combine with flat washers for even load distribution.
For precise requirements, consult engineering drawings or standards like ISO 4017 (hexagon bolts with full thread) or ASME B18.2.1.

Packing & Delivery

Bulk/Fiber Bag/Neutral packing

Carton/Box

Wood Pallet/Box

For smaller quantities, bagged packaging offers a practical solution. The fasteners are ensconced in robust plastic bags, sealed meticulously to shield the contents from moisture and dust. Each bag is clearly labeled with vital product details and quantities, facilitating straightforward handling and transport. This packaging style is ideal for workshops and retail environments, ensuring convenience and ease of use.

Boxed packaging delivers a robust and organized approach for medium to large fastener quantities. Fasteners are securely housed within durable cardboard boxes, providing an extra layer of protection against physical damage during transit. These boxes are designed for optimal stacking, maximizing storage efficiency. Each box is distinctly labeled with crucial information for easy identification and streamlined inventory management.

For large-scale shipments, palletized packaging presents an exceptionally efficient solution. Multiple boxes or bags are expertly strapped onto a pallet, forming a stable and convenient transport unit. This method is highly effective for mass distribution and storage, allowing large quantities of fasteners to be moved swiftly and safely using forklifts. The efficiency of palletized packaging minimizes handling time and reduces labor costs significantly.
