1,Description:
Differences in Thread Distribution
Full Thread: Threads extend from the screw head to the tip, providing extensive engagement area.
Half Thread: Threads cover only the lower half of the shank, with the upper section being a smooth shaft (bare shank) to reduce friction.
Performance Comparison
Secureness:
Full-thread: Dense threading provides strong engagement and more even load distribution, suitable for high-load applications (e.g., thin metal sheets, softwood furniture).
Half-thread: The smooth section reduces material compression and lowers cracking risk, but requires additional fastening with nuts and washers (e.g., battery covers, thick timber).
Installation Experience
Full-thread: High resistance, slow and laborious insertion requiring higher torque tools.
Half-thread: Low resistance, rapid installation with minimal effort (commonly termed ‘quick-thread’).
Suitable Materials.
Full-thread: Thin sheet metal, softwoods (e.g., pine) — multiple threads grip fragile materials securely.
Half-thread: Hardwoods (e.g., oak), thick metals — prevents splitting materials and reduces wear.
2,Applications:
Machinery Manufacturing: Equipment assembly, base mounting
Construction Engineering: Steel structure connections, bridge construction
Automotive Industry: Engine and chassis assembly
Electronics and Electrical: Enclosures, equipment housings
Furniture Manufacturing: Metal frame structures
Pipe Installation: Flange connections
Advantages of Use
✓ Efficient assembly and disassembly - Hexagonal head design facilitates wrench/socket tool operation with high torque transmission efficiency
✓ High load-bearing capacity - Withstands greater loads compared to other fasteners
✓ High standardisation - Complies with international standards (ISO, DIN, GB, etc.), ensuring excellent interchangeability
✓ Wide applicability - Compatible with nuts and washers of varying materials and specifications
✓ Reusable - Performance remains unaffected by normal assembly/disassembly (note fatigue damage)
Available in small packing, carton packing, or pallet configurations to meet your shipping and storage requirements.
