DYNO® FASTENERS BY APPLICATION

Dyno® ANCHOR BOLTS for structural joints in US, UK, Germany from Engineering-edge.
DYNO® ANCHOR BOLTS

High tensile carbon steel for anchoring structural supports to concrete foundations

  • Standards:
  • ASTM F1554
  • Coating Available:
  • Hot Dipped Galvanised
  • Clear Zinc
Expansion Anchors
DYNO® EXPANSION ANCHORS

Expansion anchors are high tensile carbon steel or stainless steel fasteners for structural applications designed for usage in masonry base material which provides strong holding power on expansion. Based on the requirement and operation, we can classify expansion anchor into two categories, pre-expanded and un-expanded. The pre-expanded expansion anchor is inserted in a predrilled hole compress and then exerts force to create the holding power. The un-expanded expansion anchor requires the anchor to be set after it is installed into the predrilled hole in the masonry.


  • Coating Available:
  • Hot Dipped Galvanised
  • Clear Zinc
Hex Bolts
DYNO® HEX BOLTS

High tensile carbon steel or stainless steel fasteners for structural joints

  • Standards:
  • ASTM A307
  • ASTM A325 / A490
  • ASTM A325M / A490M
  • SAE J429
  • DIN EN ISO 4014
  • DIN EN ISO 4017
  • DIN 931
  • DIN 933
  • Coating Available:
  • Hot Dipped Galvanised

Hex Nuts
DYNO® HEX NUTS

High tensile carbon steel or stainless steel nuts for bolt tightening applications.

  • Standards:
  • ASTM 194 / 194M
  • ASTM A563 / A563M
  • DIN EN ISO 4032/4033
  • DIN 934
  • Coating Available:
  • Hot Dipped Galvanised
  • Clear Zinc
  • Black Oxide
Stud Bolts
DYNO® Stud bolts

Stud Bolts are custom cut threaded fasteners commonly used with two nuts on either side, substituting a usual “bolt & nut” assembly. Carbon steel or stainless steel stud bolts are prominently used with pipes and flanges in the oil & gas industries.

  • Standards:
  • ASTM A193 / A193M
  • ASTM A320 / A320M
  • Coating Available:
  • Fluorocarbon
  • Hot Dipped Galvanised
Threaded Rods
DYNO® THREADED RODS

High tensile carbon steel or stainless steel threaded rods for structural applications.

  • Standards:
  • ASTM A307
  • DIN 975
  • Coating Available:
  • Fluorocarbon
  • Hot Dipped Galvanised
Torshear Bolts
DYNO® TORSHEAR BOLTS

Torshear bolts or TCBs are high tensile carbon steel preloaded fasteners for structural joints and are replacing conventional high strength friction grip bolts and swaged collar rivets simply because they are quick and easy to install using lightweight electric shear wrenches.


High strength TCBs are used in a wide range of applications from bridge splice plates to beam-to-column connections, from stadia roof trusses to rail switches and crossings.


The combination of superior tensile strength together with phenomenal ductility result in a universal bolt that can be employed in almost all steelwork connections.

  • Standards:
  • JSS II 09
  • JIS B1186
Washers
DYNO® WASHERS

Hardened or non-hardened carbon steel or stainless steel circular washers for surface bearing applications.

  • Standards:
  • ASTM F436 / F346M,
  • ASTM F844,
  • DIN EN ISO 7089 / 7090
  • DIN EN ISO 7091
  • DIN 125
  • DIN 127
  • DIN 128
  • DIN 6796
  • Coating Available:
  • Clear Zinc
  • Hot Dipped Galvanised
  • Black Oxide
Shear Connectors
DYNO® WELD STUDS

A shear connector is a steel projection provided on the top flange of steel composite bridge girders to provide necessary shear transfer between the steel girder and compositeslab to enable composite action.The most widely used form of shear connector is the headed stud, or shear stud. Other forms of shear connector are block and hoop, and channel connectors.

  • The advantages of shear studs over other forms of connectors are that the:
  • - Installation and welding process are quick and simple.
  • - Provides little obstruction to the slab reinforcement.
  • - Allows more satisfactory compaction of the concrete around the connectors.
  • - It provides equal shear strength in all directions.

DYNO® FASTENERS - EN 10204 COMPLIANT

Dyno® bolts and nuts for structural joints are EN10204 Compliant for US, UK, Germany. 1
Dyno® bolts and nuts for structural joints are EN10204 Compliant for US, UK, Germany 2

Mill Test Certificate (MTC) Type 3.1 is a quality assurance document certifying that the product has complied to governing standards and is validated by an independent authorized inspection representative.

DYNO® Structural fasteners with MTC Type 3.1 allows 100% traceability to ensure quality standards are met, assuring end users to procure with a peace of mind.

DYNO® RIGHTITE

Reduce the risk of over tightening with DYNO® RIGHTITE. Slip resistant and the simplest way of ensuring bolting assemblies are tensioned properly. Achieve the right tension. Suitable for A325M and A490M bolts. Best measured using a feeler or dial gauge.

DYNO® SELFLOK

Prevent self-loosening bolted joints with DYNO® SELFLOK. The bevelled design strengthens the interlocking system that resists vibration and secure bolts tightly — even during extreme vibrations or dynamic loads.

DYNO® SELFLOK for anti-vibration bolt joint applications:

  • Steel or stainless steel
  • Low tightening torque
  • Easy installation

More efficient than conventional washers, DYNO® SELFLOK can save overall time and maintenance cost.
