Our Range of Fasteners

Hex Bolts

ASTM A193

  • ASTM A193 is widely used to construct a bolted joint
  • It provides axial clamping force with a nut
  • The shank of the bolt acts as a dowel
  • A joint is pinned against sideways shear forces
ASTM A193 HEX BOLT Dimensions:
  • DIA: Various sizes from M-6 to M-52
  • H: Ranges from Min 3.85 to Max 33.50
  • F: Ranges from Min 9.78 to Max 80.00
  • C: Ranges from 11.05 to 88.25
  • WD: Ranges from Min 0.15 to 1.00
  • R: Ranges from 0.25 to 1.60
  • MIN: Varies based on the size of the bolt
  • MAX: Varies based on the size of the bolt

ASTM A325M

  • Metric heavy hex bolts for structural applications (ASTM A325M specifies requirements for these bolts).
  • Made from quenched and tempered steel (ensures high strength).
  • Available in diameters M16 to M36 (metric sizing).
  • Used in bolted joints with nuts to create strong connections (axial clamping force and shear resistance).

ASTM A490

  • High-strength alloy steel bolt: ASTM A490 refers to a heavy hex bolt specifically made from high-strength alloy steel for demanding structural connections.
  • Stronger than A325 bolts: Compared to the common A325 structural bolts, ASTM A490 offers superior strength due to its alloy steel composition.
  • Applications in structural steel joints:  These bolts are ideal for heavy-duty bolted joints in structural steel applications.
  • Shorter thread length for specific use: Unlike standard hex bolts, ASTM A490 bolts feature shorter thread lengths to optimize their use within structural joints.

DIN 933

  • Metric heavy hex bolts for structural applications (ASTM A325M specifies requirements for these bolts).
  • Made from quenched and tempered steel (ensures high strength).
  • Available in diameters M16 to M36 (metric sizing).
  • Used in bolted joints with nuts to create strong connections (axial clamping force and shear resistance).
Heavy Hex Bolt ASTM A325M, ASTM A490, and DIN 933 Dimensions:
  • DIA: Various sizes from M-16 to M-36
  • D2: Ranges from Min 15.30 to Max 37.00
  • T: Ranges from Min 31.00 to Max 63.00
  • H: Ranges from Min 9.25 to Max 23.55
  • F: Ranges from Min 26.16 to Max 60.00
  • C: Ranges from 29.56 to 66.44
  • W: Ranges from 24.90 to 55.90
  • WD: Ranges from Min 0.40 to Max 0.80
  • F: Ranges from 0.60 to 1.50
  • MIN: Varies based on the size of the bolt
  • MAX: Varies based on the size of the bolt

CSK Bolt

  • Flat head for smooth surfaces: CSK bolts sink into the material, creating a flat finish.
  • Common in construction: Used in railings, decks, and walkways for a clean look.
  • Many sizes available: Find the perfect CSK bolt to fit your project.
  • Strong and dependable: Made from various materials for different needs.
CSK FLAT HEAD BOLT DIN 7991 Dimensions:
  • DIA (D): Various sizes from M-4 to M-24
  • H: Ranges from 2.3 to 14
  • HD: Ranges from Min 7.64 to Max 39
  • RADIUS UNDER HEAD: Ranges from 0.2 to 1.6
  • NOMINAL KEY SIZE: Ranges from 2.5 to 14
  • K: Ranges from Min 2.52 to Max 14.212
  • SOCKET DEPTH: Ranges from Min 1.55 to Max 10.3

CSK Bolt

  • Hexagonal hole instead of slot: Allen bolts have a hollowed-out hexagonal head, requiring an Allen key to tighten.
  • Strong grip: The hex design allows for a powerful grip and high torque.
  • Clean look: No slot on the head creates a smooth, finished appearance.
  • Common uses: Found in machinery, furniture, and more for secure fastening.
Allen Bolt DIN 912 Dimensions:
  • DIA (D): Various sizes from M-5 to M-48
  • H: Ranges from Min 4.82 to Max 48.00
  • HD: Ranges from Min 8.28 to Max 72.00
  • NOMINAL KEY SIZE: Ranges from 4.00 to 36.00
  • K: Ranges from Min 4.02 to Max 36.33
  • SOCKET DEPTH: Ranges from Min 2.5 to Max 28

Carriage Bolt

  • Mushroom head, square neck: Carriage bolts have a rounded head and a square section under the head.
  • Grips wood (and metal): The square neck prevents the bolt from spinning in wood and can lock into a square hole in metal.
  • One-sided access: Tightened with a nut on the threaded end, ideal when you can’t reach the head.
  • Strong and secure: Often used for heavy-duty applications like beams and hinges.
Carriage Bolt Din 603 Dimensions:
  • DIA (D): Various sizes from M-5 to M-20
  • H: Ranges from Min 2.70 to Max 11.05
  • HD: Ranges from Min 12.45 to Max 46.80
