8 x ½ Pan Head Phillips Truss Screw Zinc Plated CR3+

The 8 x ½" Pan Head Phillips Truss Screw is an industrial-grade fastener designed for general-purpose assembly and fabrication. Its wide, low-profile truss head provides a large bearing surface, making it ideal for securing thin materials without pull-through, while the zinc plating offers durable corrosion resistance.

  • Low Carbon Steel Construction
  • Zinc Plated Finish (ASTM B633)
  • CR3+ Trivalent Chromium Passivate (RoHS Compliant)
  • Pan Head Truss Design for Wide Bearing Surface
Overview | Specifications | Applications | Finish Options | How to Measure | Order Checklist

Manufactured from durable low carbon steel, this truss screw is engineered for reliability in MRO and light-duty fabrication applications. It undergoes a zinc plating process according to ASTM B633 standards, which deposits a protective zinc layer to guard against rust and corrosion. The process is completed with a CR3+ trivalent chromium passivate, an environmentally safer coating that enhances corrosion protection and provides a clean, bright finish, while also ensuring RoHS compliance for use in electronics and other regulated industries.

The distinctive feature of this screw is its truss head, which combines a low-profile dome with a wide, flat bearing surface underneath. This design is perfect for applications involving thin gauge sheet metal, plastics, or wood composites, as it distributes clamping force over a larger area to prevent damage or pull-through. The Phillips drive allows for easy installation with standard tools, making these screws a go-to choice for electrical enclosures, machinery guards, cabinetry, and general assembly tasks where a secure, flush-fitting fastener is required.

Specifications

  • Material: Low Carbon Steel
  • Standards: ASTM B633 (for Zinc Plating), ANSI/ASME B18.6.3 (Dimensional)
  • Strength/Tensile: Approx. 60,000 psi (Comparable to Grade 2)
  • Dimensions: Diameter: #8, Length: 1/2 inch
  • Finish: Zinc Plated with CR3+ Trivalent Chromium Passivate
  • Certifications: RoHS Compliant

Applications

  • Fabrication: Assembling sheet metal enclosures, brackets, and light-gauge steel frames.
  • Electronics: Securing components, panels, and chassis where a wide, low-profile head is needed.
  • MRO (Maintenance, Repair, Operations): General repairs on machinery, equipment guards, and facility fixtures.
  • Woodworking & Cabinetry: Attaching hardware, drawer slides, and backing panels.

Target Users

Fabricators, maintenance technicians, electricians, and assembly line workers rely on these truss screws for their versatility and secure fastening capabilities in a wide range of commercial and industrial projects in the Los Angeles area.

Finish Options

This product comes standard with a clear zinc plated finish enhanced by a CR3+ passivate for superior corrosion resistance and a bright appearance. For specific project requirements, other finishes such as black oxide or yellow zinc may be available via special order. Contact our Los Angeles sales team for custom finish inquiries.

How to Measure

To correctly specify a truss screw, you need two key measurements: 1) Diameter (e.g., #8), and 2) Length (measured from directly under the head to the tip, e.g., 1/2 inch). Ensure you also specify the head type (Truss), drive type (Phillips), and desired finish.

Example: To order this screw, specify "8 x 1/2 Pan Head Phillips Truss Screw, Zinc Plated".

Order Checklist

  • Product name and required dimensions (#8 x ½")
  • Material specification and quantity (Boxes or Bulk)
  • Confirm drive type (Phillips)
  • Surface finish requirements (Standard Zinc CR3+)
  • Certifications required (Certificate of Conformance)
  • Special handling or delivery requirements
