5/16" X 2" ONE WAY SCREW STEEL FINISH BLACK

Secure your fixtures and equipment with our 5/16" x 2" One-Way Steel Screws. Featuring a tamper-resistant drive that only allows for installation, these fasteners are ideal for public-facing applications where security is paramount. The durable black finish provides moderate corrosion resistance and a clean, professional look.

  • Tamper-Resistant One-Way Drive
  • Low Carbon Steel
  • Based on ASTM A307
  • Protective Black Finish
Overview | Specifications | Applications | Finish Options | How to Measure | Order Checklist

This 5/16" x 2" one-way screw is manufactured from low carbon steel, offering reliable performance consistent with ASTM A307 standards for general-purpose fasteners. The key feature is its unique head design, which can be installed with a standard slotted screwdriver but cannot be removed, making it an effective tamper-proof solution. Its construction ensures dependable strength for light to medium-duty fastening in metal, wood, and plastic substrates. The protective black finish adds a layer of corrosion resistance suitable for indoor or controlled environments.

Designed specifically for security and loss prevention, these one-way screws are the professional choice for installing permanent fixtures in public spaces. Common uses include securing signs, bathroom partitions, license plates, and protective casings for electronics. Their tamper-resistant nature makes them essential for MRO and facilities management in commercial buildings, schools, and transit systems, preventing vandalism and theft of valuable assets. This makes them a key component for construction hardware needs in the Los Angeles area.

Specifications

  • Material: Low Carbon Steel
  • Standards: ASTM A307 (for material properties)
  • Strength/Tensile: Approx. 60,000 psi minimum
  • Dimensions: Diameter: 5/16", Length: 2"
  • Finish: Black Oxide or Similar Protective Coating
  • Certifications: Material certifications available upon request

Applications

  • Public Fixtures: Securing signs, plaques, benches, and directories in parks, transit stations, and public buildings.
  • Loss Prevention: Fastening retail displays, electronic enclosures, and access panels to prevent tampering.
  • Institutional Security: Installing bathroom partitions, wall plates, and fixtures in schools, hospitals, and correctional facilities.
  • Automotive/Vehicle: Attaching license plates, custom frames, and accessory panels permanently.

Target Users

These industrial-grade security fasteners are used by facilities managers, MRO technicians, contractors, and fabricators for projects requiring a permanent, non-removable fastening solution to prevent vandalism, theft, or unauthorized access.

Finish Options

This commercial screw comes standard with a durable black finish (typically black oxide) for a clean appearance and moderate corrosion resistance. For applications requiring higher corrosion protection, similar tamper-resistant screws may be available in zinc-plated steel or stainless steel by special order.

How to Measure

To specify the correct screw, measure the required Diameter (the shank's thickness, here 5/16") and the Length (from underneath the head to the tip of the screw, here 2"). Ensure the one-way drive is suitable for your permanent installation needs.

Example: To order, specify the product as '5/16" x 2" One-Way Screw, Steel, Black Finish'.

Order Checklist

  • Product name and required dimensions (e.g., 5/16" x 2")
  • Material specification and quantity
  • Drive type confirmation (One-Way)
  • Surface finish requirements (Black)
  • Certifications required (if any)
  • Confirm same-day pickup or delivery requirements
