Steel Fasteners

Steel fasteners provide critical mechanical connections in structural steelwork, equipment installation, concrete anchoring, and general construction assemblies. These components support reliable load transfer, alignment, clamping force, and structural continuity across commercial, industrial, municipal, and infrastructure projects.

Central Steel Supply Company stocks specification-compliant steel fasteners in multiple grades, materials, and finishes. The following sections outline available fastener types, specifications, and applications.

Dimensions, Grades, and Value-Added Support

Fastener Types and Availability

Central Steel Supply Company stocks a broad selection of fasteners and can coordinate additional items through trusted partner resources, providing a comprehensive, one-stop source for structural steel erection, equipment anchoring, fabrication assemblies, and general-purpose construction requirements.

• Hex Head Lag Screws: Hex head lag screws provide secure anchoring into wood or softer substrates and are commonly used for structural attachments, hardware installation, and equipment mounting where a threaded connection is required without a pre-tapped hole.
• Bent-Leg Anchor Bolts: Bent-leg anchor bolts provide reliable anchorage into concrete foundations for structural steel columns, equipment bases, handrail posts, and other embedded systems. These anchors are supplied in multiple diameters, lengths, and bend configurations depending on project requirements.
• Hex Head Cap Screws & Hex Head Bolts: Hex head cap screws and hex head bolts appear similar but serve different purposes:
  • Hex Head Cap Screws (HHCS): Manufactured with tighter dimensional tolerances and a machined bearing surface under the head, supporting precise clamping and alignment.
  • Hex Head Bolts: Designed for general-purpose structural and assembly use with broader tolerances suitable for standard bolted joints.

  Both fastener types are available in multiple diameters, lengths, grades, and finishes for structural framing, equipment attachment, and connections involving steel and adjacent materials.

• Threaded Rod: Threaded rod supports tension bracing, hanging systems, equipment mounting, and general-purpose fastening across structural, mechanical, and electrical applications. Material is stocked in standard lengths and can be supplied in multiple grades and finishes.
•  Nuts:
  • Hex Nuts: General-purpose fastening for standard bolts and threaded rod
  • Heavy Hex Nuts: Larger bearing surface and thicker body to support high-strength bolting and structural applications
• Washers:
  • Standard Flat Washers: Distribute load under bolt heads and nuts for general construction
  • Structural Flat Washers: Thicker, larger-diameter washers designed for high-strength structural bolting
  • Spring Lock Washers: Provide tension and vibration resistance for assemblies requiring additional security

Common Fastener Grades

• Bolts, Cap Screws & Threaded Rod:
  • Grade 2, Grade 5, Grade 8
  • A307 (general-purpose construction)
  • A325 (structural bolt)
  • A490 (high-strength structural bolt)
  • B7 (alloy threaded rod for high-temperature or high-pressure applications)
• Nuts:
  • Grade 2, Grade 5, Grade 8
  • A563 (hex and heavy hex)
  • A194 (alloy nuts paired with B7 rod)

Finishes

Fasteners are stocked in several finish types to support application-specific corrosion protection requirements:

• Plain (Uncoated) Steel
• Zinc-Plated
• Hot-Dipped Galvanized

Additional finishes or coated systems can be coordinated through trusted partner resources when specialized protection is required.
