Partial Thread Screw Half Thread Machine Screw for Equipment Frame and Plastic Housing Assembly
Product Overview
⚙️ Professional Fastening Solution
Partial Thread Screw is a customized machine fastener designed with smooth full shank on upper part and precise machine thread on the tail, widely adopted across multiple industrial fastening fields. Unlike full thread machine screws, the unthreaded shaft of Partial Thread Screw avoids scratching through holes and effectively prevents plastic cracking during tight installation. Manufacturers select our half thread fasteners for reliable fixed connection of metal and composite components.
We produce standard and custom-size Partial Thread Screw with diverse surface treatments including zinc plating, stainless steel raw finish and black oxide coating to match different corrosion resistance requirements from global B2B buyers. All raw materials pass strict raw material inspection to guarantee stable mechanical property for long-term equipment operation.
Core Features & Advantages
Smooth unthreaded shank design: The non-threaded rod section of Partial Thread Screw goes through workpiece through-hole freely without damaging hole inner wall, perfectly solve the common pain point of shell crack caused by full thread squeezing.
Controllable locking depth: Fixed shank length limits screwing travel, avoiding over-tightening damage on thin plastic and thin sheet metal parts.
High shear resistance: Solid smooth shaft greatly improves shear strength compared with full thread counterparts, suitable for load-bearing fixture assembly.
Flexible customization: We support non-standard length, head type and thread pitch customization of Partial Thread Screw to satisfy unique industry assembly needs.
