Product Overview
Thread Cutting Screws cut their own mating internal thread into a pre-drilled hole through the cutting feature on the thread as they are driven in, forming a firm bite without pre-tapping for high assembly efficiency. Cold heading plus thread rolling produces a clear thread profile and complete cutting structure; used for fastening automotive parts, electronics and electrical appliances, hardware and thin-sheet structures, customizable by thread size, length and head style.
Core Advantages
Cuts its own mating thread into the pre-drilled hole, eliminating a separate tapping step and reducing assembly steps for line-volume fastening.
Cold heading plus rolling gives a clear thread profile and stable bite with good bending and fatigue resistance and long service life.
Thread size, length and head style can be customized from drawings or samples, suiting different plate thicknesses and pre-drilled holes.
Application Scenarios Scenario
Self-tapping fastening of automotive parts and sheet-metal parts.
Connection of electronics and appliance housings and brackets.
Assembly of hardware, furniture and thin-sheet structures.
Quality Control
Certified to ISO 9001, IATF 16949, ISO environmental management system and RoHS. Screws are checked batch by batch with a thread gauge for thread profile, verifying complete cutting structure, defect-free head and correct length; wire is inspected incoming, cold heading and rolling patrolled, products pass salt-spray testing for rust resistance, thread and appearance spot-checked before dispatch; custom parts undergo 100% inspection before packing, and key characteristics are controlled under APQP, PPAP, FMEA and SPC.
Packaging & Delivery
Screws are rust- and moisture-sealed in fixed-quantity bags or boxes before thickened export cartons, preventing thread friction damage; bulk quantities are stretch-wrapped on pallets; outer cartons print marks, batch number and quantity. EXW, FOB, CIF and CFR are supported. Standard orders take about one week and bulk orders about one month; after sample approval, custom parts deliver in 10-15 working days for simple structures and 20-30 working days for complex structures.
FAQ
Q1: Is pre-tapping needed before driving?
A: No. Thread cutting screws cut their own mating thread into the pre-drilled hole, eliminating pre-tapping.
Q2: How is rust resistance?
A: Products pass salt-spray testing with corrosion and rust resistance; surface treatment can be customized on request.
Q3: What about warranty and after-sales?
A: Under normal use the warranty is 12 months; material or workmanship defects are replaced or reshipped free of charge with a dedicated contact.
