Production Process of Custom Bolts:
Custom bolts are typically produced through pPrecision Machining:  CNC (Computer Numerical Control) machines, Cold Forging, Hot Forging, Thread Rolling, Injection Molding. This involves shaping metal blanks into the desired bolt shape, threading the shaft, and applying any necessary surface treatments or coatings.
Characteristics:
Custom bolts offer unique specifications tailored to specific application requirements. They may feature specialized threading, head shapes, or dimensions to provide optimal performance in diverse industrial settings.
Appearance and Shape:
Custom bolts (Non-standard bolts)  can have unique lengths, diameters, and thread pitches tailored to the needs of the application.
Specialized Threads: Bolts may feature standard or custom thread profiles, with threaded or unthreaded shafts, such as metric, UNC (Unified National Coarse), UNF (Unified National Fine), or ACME threads, depending on the mating components and load requirements.
Head Styles: Bolts can have different head styles, including hexagonal, square, round, countersunk, or flanged heads, designed for specific fastening methods and aesthetics.
Drive Types: Bolts may incorporate various drive types, such as hex socket, slotted, Phillips, Torx, or Allen (hexagon socket) drives, to accommodate different installation tools and torque requirements.
Materials:
Custom bolts can be manufactured from a wide range of materials, including Steel, Stainless steel, Aluminum, Brass, Copper, Titanium, Nickel, Alloy steel, Zinc, Bronze. Material selection depends on factors such as strength, corrosion resistance, temperature resistance, and the specific requirements of the application.
Usage Areas:
Custom bolts find applications in numerous industries, including automotive, aerospace, construction, marine, and electronics. They are utilized in assemblies, structures, machinery, equipment, and infrastructure where standard off-the-shelf bolts may not meet the required specifications.
Surface Treatment:
Custom bolts may undergo surface treatments such as Plating, Coating, Passivation, Anodizing, Galvanizing, Phosphating, Blackening, Chromating, Nitriding, Oxidation coating, Zinc-Nickel plated, Dacromet,  to enhance corrosion resistance and appearance. Common treatments include zinc plating, galvanizing, black oxide coating, or passivation, depending on the material and environmental conditions.
Salt Spray Test Duration:
The salt spray test duration for custom bolts depends on factors such as material composition, surface treatment, and application requirements. are subjected to salt spray testing to assess their corrosion resistance. It typically ranges from 24hours to 1500hours to ensure durability in corrosive environments to assess the bolts' corrosion resistance and suitability for use in harsh environments.
