Grip-Rite Pro-Twist No. 8 x 1/2 in. Phillips Truss Head Coarse Lath Screws are engineered for outdoor lath-and-plaster applications, delivering fast, secure fastening with a durable zinc-plated finish that stands up to the elements.
Distinctive features that accelerate your project
-
Self-drilling tip enables rapid penetration through wood lath into studs, cutting installation steps and saving time on every project.
-
Phillips drive provides reliable torque with reduced cam-out, so screws seat cleanly every time—even in tight spaces.
-
Truss head design offers a wide bearing surface to distribute load and prevent pull-through in plaster or lath assemblies.
-
Coarse thread delivers strong bite in wood lath and surrounding material, ensuring solid holding power for exterior builds.
-
Zinc-plated finish delivers corrosion resistance in outdoor environments, helping your lath-and-plaster system endure seasonal exposure.
-
No. 8 x 1/2 in. size is a versatile choice for standard lath thicknesses and typical stud spacing, balancing insertion ease with durability.
-
Pro-Twist construction promotes quicker driving and consistent thread engagement, reducing driver wobble and fatigue on longer runs.
Ideal uses and applications
- Attaching exterior plaster lath to wood framing in stucco or plaster projects.
- Replacing damaged lath fasteners during exterior renovations or retrofits.
- Securing metal or wood lath in new construction where a robust, rust-resistant fastener is required.
- Any outdoor application where a reliable, fast-install screw with strong holding power is needed.
Practical installation tips
- Use a Phillips bit for steady driving and to minimize cam-out; a typical cordless drill/driver works well for most jobs.
- Rely on the self-drilling tip to pre-engage the material; reserve pre-drilling only for unusually hard surfaces or very thick plaster.
- Avoid over-torquing to prevent distortion of the truss head and to maintain optimal bearing on the lath surface.
- Pair with compatible fasteners and sealants recommended for outdoor plaster systems to maximize longevity.
