R.R.Steel Industries

Material: Mild steel – strong and cost-effective, but typically coated (e.g., zinc-plated) for corrosion resistance, especially in damp environments

Thread Type: Coarse thread – designed to create a strong grip in PVC or other plastic materials, ensuring a secure fastening without causing cracking

Head Type: Typically pan head, round head, or countersunk head, depending on the application and surface flushness requirements

Drive Type: Commonly Phillips or Pozidriv – providing a secure fit for the screwdriver or power drill to prevent slipping

Length: Varies depending on the specific application (typically between 25mm and 50mm for fixing PVC); length chosen based on material thickness and required penetration

Shank Type: Often partially threaded, with the unthreaded portion allowing smoother compression and alignment between the PVC and surface material

Finish: Mild steel with a corrosion-resistant coating like zinc or black oxide for outdoor or exposed use

Usage:

Fixing PVC pipes, fittings, or panels to wooden, metal, or plastic surfaces

Securing PVC trim, frames, or cladding to walls or structures

Used in plumbing, electrical installations, or construction where PVC materials need to be fastened

Advantages:

Coarse thread ensures a tight, secure hold without damaging the PVC

Mild steel provides strength, while corrosion resistance coatings increase longevity

Easy to install with a standard screwdriver or drill, offering quick fastening solutions for PVC applications

Length: 13mm – short screw, ideal for fastening thin materials or shallow penetration applications

Material: Mild steel – strong and economical for indoor or dry environments; often zinc-plated for basic corrosion resistance

Head Type: Pan head – flat top with rounded edges and a wide bearing surface, providing a neat, low-profile finish

Drive Type: SDS (Self Drilling Screw) – features a drill-like point that eliminates the need for pilot holes in thin metal or wood

Thread Type: Self-tapping / self-drilling, with sharp threads designed to cut through material and secure tightly

Application Surface: Ideal for metal-to-metal, metal-to-wood, or plastic-to-metal connections in light-duty uses

Usage:

• Electrical boxes and brackets

• Sheet metal assembly

• HVAC and ductwork fastening

• Fixing components to thin steel or aluminum profiles

Advantages:

• Quick installation – no pre-drilling needed

• Pan head offers a clean look and reduces risk of pull-through

• Mild steel provides good mechanical strength at low cost

Length: 13mm (measured from under the head to the tip) – short screw for light-duty applications and thin materials

Material: Mild steel – strong and economical; may be zinc-plated or otherwise coated for basic corrosion resistance

Head Type: Truss head – wide, slightly domed head with a large bearing surface to prevent material pull-through

Drive Type: Commonly Phillips or slotted – compatible with standard screwdrivers or power tools

Thread Type: Typically coarse thread, designed for use in wood, plastic, thin metal, or with anchors in light-duty applications

Finish: May be zinc-plated, black oxide, or painted depending on intended use or appearance needs

Usage:

Fixing sheet metal, cable clamps, or brackets to wood or plastic

Assembling light fixtures, electrical boxes, or small enclosures

Suitable for decorative applications where a wide, low-profile head is preferred

 

Advantages:

Truss head distributes load and prevents material damage

Short length ideal for thin or delicate materials

Cost-effective and easy to install for general-purpose fastening
