1. Core customization parameters
Brass material type: H59/H62, the default is H62, because H62 has higher ductility
Optional surface treatment: natural polishing, nickel plating, gold plating
Dimensions
Diameter range: M1~M3, support 0.1mm Customized
Length range: 2~20mm, adjustable head thickness, default head diameter = 2 times thread diameter
Groove requirements
Slot width: 0.3mm (M1)~1.2mm (M3)
Groove depth: 1/3 of head thickness can be deepened to 1/2 anti-slip teeth
2. Advanced options
Special structure
Non-standard head type: flat head/round head/countersunk head
Thread type: fine pitch/coarse pitch/self-tapping thread
Performance enhancement
Salt spray test: 48~96 hours, can reach ASTM after nickel plating, B633 standard
Torque requirement: ≥0.1N·m (M1) ~ 0.5N·m (M3)
Logo and packaging
Head laser marking: LOGO/batch number (depth ≤0.05mm)
Packing method: blister tray (1000pcs/tray)/roll (with adhesive backing)
III. Production and quality inspection
Process standard
Tolerance: ±0.02mm (diameter), ±0.05mm (length)
Thread inspection: full inspection of go/no-go gauges
Delivery time and minimum order quantity
MOQ: 5000pcs (standard model can accept 1000pcs s trial order)
Production cycle: 7~15 days (non-standard design + 3 days)
Certification support A
RoHS/REACH report can be provided
IV. Precautions
Design suggestions
It is recommended to use magnetic tools with screws below M1.4
Nickel plating is recommended for high-frequency disassembly scenarios
Risk warning
Brass has a low hardness (HV110-150) and is not suitable for ultra-high torque scenarios
Special plating is required in extreme environments
This solution takes into account both technical details and procurement decision-making efficiency, and can further simplify or expand specific modules according to actual needs.
