Connection Technology Experts – More Than Just Fasteners, Providing Full-Lifecycle Engineering Support

Leveraging professional laboratories and a seasoned application team, we offer highly reliable connection solutions for the construction, automotive, new energy, construction machinery, and rail transportation industries, helping customers improve assembly efficiency and reduce overall costs.

  • AutoCAD
    01

    Design & Simulation

    It's not just about selling standard parts; it's about assisting customers with selection calculations (such as torque, clamping force, and fatigue strength), providing custom non-standard parts (cold heading, turning, and heat treatment), and offering selection advice for special working conditions (high temperature, corrosion, and anti-loosening).

  • Detection
    02

    Detection & Verification

    Demonstrate laboratory capabilities such as salt spray testing, friction coefficient testing, metallographic analysis, hardness testing, transverse vibration testing (anti-loosening testing), and torque-clamping force testing.

  • Assembly
    03

    Process & Assembly

    We offer process optimization for customer assembly lines (whether manual or automated tightening machines). For example, we provide pre-applied adhesive services to reduce adhesive application steps on the production line, or we offer kitting to reduce small parts management costs on customer assembly lines.

  • Inventory

From loose and hidden dangers to solid as a mountain——Irving project anchoring practice

Engineering Services01
Client: Irving Construction Group
Product: High-strength rear expansion bolt (specification: M12×110, grade 5.8 galvanized)

Background: The dry-hanging renovation of the exterior wall of a 12-story commercial building along the coast requires 3,200 anchor points, the wind pressure is ≥1.5kN/㎡, and the construction period is only 20 days.

Challenge: The wall contains hollow bricks and cracked concrete. Ordinary bolts are easy to slip and have insufficient pullout resistance. The chemical anchors have a maintenance period of 4 hours/point and cannot be delivered on time.

Plan: Use rear-expanded mechanical expansion bolts to form an interlocking structure; use a torque-controlled electric drill (55N·m); add hot-dip galvanizing + sealing layer (salt spray ≥ 1000 hours).
  • 56 %
    Pull-out force 18.7kN, exceeding design standard by 56%, with no cone-shaped failure.
  • 55 %
    3200-point installation completed in just 9 days, saving 55% of labor time compared to chemical anchors.
  • 32 %
    Overall cost reduced by 32%.

From Hazardous to Rock-Solid – Murphy Thatcher Self-Tapping Screw Application Practice

Client: Murphy Thatcher 

Product: High-strength self-tapping screw (Specification: ST6.3×50, twin-thread, carbonitriding surface treatment)

Background: Exterior wall insulation retrofitting of a 5‑story office building in a certain city. 5,800 fixing points required, wind load requirement ≥1.8 kN/㎡, project duration only 15 days.

Challenges: Base substrate consists of lightweight concrete and old plaster layer. Ordinary screws are prone to slipping and insufficient torque leading to fixing failure. Pre‑drilling is time‑consuming and generates heavy dust pollution. Traditional expansion anchors have poor grip in thin‑walled substrates and cannot meet pull‑out requirements.

Solution: Use of Murphy Thatcher custom self‑tapping screws. With a self‑drilling pointed tip and twin‑thread design, they integrate drilling, tapping, and locking in one step. Paired with a high‑precision impact drill (set torque 40 N·m, speed 1,800 rpm). Surface treatment: carbonitriding + epoxy coating, passing 1,200 hours of salt spray test.
  • 68 %
    Pull‑out force reaches 4.2 kN, exceeding the design standard by 68%, with no cracking or edge breakage of the substrate.
  • 62 %
    5,800 fixing points completed in just 7 days – saving 62% in labor time compared to the traditional “pre‑drilling + expansion anchor” method.
  • 45 %
    Total cost reduced by 45%, while also eliminating dust disposal expenses associated with pre‑drilling.
