Product Description

Our M3.5 fine thread drywall screw rolling dies are purpose-built for high-volume drywall fastener production. The double-start, single-out design combines the speed advantage of dual-thread feeding with the precision of single-exit forming—making it the preferred choice for manufacturers who need both throughput and thread quality.

Double Start, Single Out – How It Works

- Double Start : Two thread leads are formed simultaneously, effectively doubling the feed rate per machine stroke. This significantly increases production output compared to single-start dies.

- Single Out : Despite the dual-feed design, each stroke produces one finished screw. This ensures the thread geometry, pitch accuracy, and surface finish are not compromised by simultaneous multi-piece forming.

Fine Thread for Drywall Applications

Fine thread drywall screws (typically with a higher threads-per-inch count than coarse thread) are designed for fastening gypsum board to metal studs. They require:

- Consistent thread depth and sharp crest formation

- Smooth thread surface to reduce driving torque

- Accurate pitch control to prevent cross-threading

Our dies deliver all of the above through precision CNC grinding and tight tolerance control.

M2 HSS – Built for Continuous Production

Made from M2 high-speed steel with optimized heat treatment (62–64 HRC), these dies resist wear and deformation under high-pressure cold forming. The material choice ensures stable performance across long production runs with minimal dimensional drift.

Mlti-Length Compatibility

A single die set supports M3.5 × 16 / 19 / 25 / 32 mm screw lengths, reducing the need for multiple die inventories. Custom length ranges can be accommodated upon request.

Key Features

- ✅ Double-start design → Higher feed rate, increased output per hour

- ✅ Single-out forming → Maintains thread accuracy and surface quality

- ✅ Fine thread profile → Ideal for drywall-to-metal stud fastening

- ✅ M2 HSS construction → Long service life under continuous operation

- ✅ Multi-length coverage → One die for 16/19/25/32 mm screws

- ✅ Low scrap rate → Stable pitch and major diameter control

Applications

- Drywall screws (fine thread, phosphate/black oxide coated)

- Gypsum board to steel stud fastening

- Interior construction and partition wall systems

- Wood-to-metal fastening where fine thread is preferred
