Products Description
C2800 Introduction
Brass is a versatile copper-zinc alloy series with comprehensive mechanical and physical properties, including excellent
electrical and thermal conductivity, structural strength, surface hardness, wear resistance, ductility and outstanding corrosion resistance. Brass materials feature rich and adjustable surface colors ranging from yellow, red, silver to golden tones, which are widely adopted by designers and architects to optimize interior and exterior decorative effects for architectural projects. UNS C28000 (C2800) is a high-quality standard yellow brass alloy within the brass material system. It inherits superior ductility and stable machinability, supporting precision stamping, bending, forging and pressing forming processes. With uniform material texture, bright polishing performance and reliable atmospheric and freshwater corrosion resistance, C2800 brass maintains stable mechanical performance and long service life under conventional working conditions. Widely applied in plumbing pipe fittings,press-fit pipeline components, architectural decorative hardware, instrumentation accessories, valve parts and general mechanical engineering components, UNS C28000 brass serves as a cost-effective and multi-functional alloy for industrial connection and architectural decoration scenarios

C2800 Brass Half Threaded Hex Bolt Introduction
A Half Threaded Hex Bolt, also known as a hexagon head bolt with partial thread, is a common fastener with a hexagonal head and a shank consisting of a smooth unthreaded section and a threaded section. The hexagonal head allows torque to be applied easily with wrenches for tightening and disassembly. The unthreaded shank provides higher shear strength and better alignment, while the threaded segment mates with nuts to create clamping force.
This bolt is made of brass C2800, featuring good machinability, excellent corrosion resistance and non‑magnetic properties. It complies with standards such as ASTM A325, ASTM A490, ISO 4014 and GB/T 5782. Optional surface treatments can be provided upon request, including polishing and anti‑tarnish coating to prevent surface oxidation.
It is widely used for structural assembly, machinery, equipment installation, marine and plumbing applications where corrosion resistance is required. Custom dimensions, thread lengths and finishes can be offered to meet various engineering requirements.

C2800 Brass Half Threaded Hex Bolt Product Processing
1.Raw Material Inspection & Blanking:
Adopt high-quality brass rod materials with stable copper-zinc alloy composition. Strictly inspect surface smoothness, internal density and mechanical properties to exclude cracks, pores and impurity defects. Cut qualified brass rods into standard fixed-length blanks to ensure consistent size for subsequent forging and forming.
2.Pretreatment & Hot Heading Forming:
2.Pretreatment & Hot Heading Forming:
Clean and lubricate brass blanks to remove surface oil stains and oxides. Adopt precision hot heading process to integrally form standard hexagonal head and smooth unthreaded shank. Strictly control forming temperature to ensure compact structure, regular head shape and no deformation.
3.Trimming, Shaping & Half Thread Rolling:
3.Trimming, Shaping & Half Thread Rolling:
Remove surface burrs and sharp edges after forming. Calibrate hexagon flatness and shank straightness to ensure accurate assembly size. Adopt precision thread rolling process to produce standard half-thread section, with neat thread profile and uniform pitch, ensuring stable matching with nuts.
4.Stress Relief & Polishing Treatment:
4.Stress Relief & Polishing Treatment:
Conduct professional stress relief treatment to eliminate internal residual stress generated during forming and thread processing. Fine polish the bolt surface to improve smoothness, remove processing traces and enhance brass texture and oxidation resistance.
5.Full-Range Performance & Appearance Inspection:
5.Full-Range Performance & Appearance Inspection:
Inspect key dimensions including hex size, shank diameter and thread tolerance. Check thread meshing performance, surface finish and structural stability. Screen out defective products with deformation, burrs and unqualified threads to meet industrial fastening standards.
6.Sorting, Packaging & Warehousing:
6.Sorting, Packaging & Warehousing:
Automatically sort qualified brass half threaded hex bolts by specifications. Adopt dust-proof, moisture-proof and anti-collision packaging to protect thread teeth and polished surface. Label each batch with complete specification and batch information, then store and deliver products after final verification.
