Screwdriver Bit FAQ
Q1Which drive families do you offer?
As standard: Phillips (PH), Pozidriv (PZ), TORX®, slotted (SL), hex (HEX) and hex socket bits, plus non-standard drives developed to sample or drawing.
Q2What shank sizes and lengths are available?
Common shanks are C4, C5 and C6.3 (1/4 inch), with blade lengths from 25 mm to 150 mm. Choose by power tool or workstation requirement; special sizes can be customized.
Q3What material and heat treatment do you use?
Quality alloy tool steel, heat-treated and surface-finished for stable hardness and wear resistance. Specific material and hardness are set by service conditions and customer standards.
Q4How do I choose between PH1, PH2 and PH3?
Match the bit size to the screw head: PH0/PH1 for small electronics, PH2 for appliances and general assembly, PH3/PH4 for larger screws. A mismatched size cams out and damages the screw head.
Q5Do you support custom bits?
Yes. With a complete bit line in house we customize special drives, lengths, magnetism and finishes to drawing or sample, with volume supply capability.
Q6How do I get a quotation and samples?
Contact our sales team with bit type, size, quantity and application: Mr. Zhang +86 13510369429, Mr. Fan +86 13560730094, or email Louis.Liu@zcjtech.com.
