Select by bore size, thread engagement, and pack quantity.
What is a HAKKO TV-553C Standard Bore Haltec?
A HAKKO TV-553C Standard Bore Haltec is a flange-bolt fastening reference used to specify the correct STANDARD 18-8 stainless steel flange bolt for a given bore and clamping application. The bolt's integrated washer face distributes clamping load without a separate washer, making it suitable for machinery, piping flanges, and structural connections.
In practice, buyers searching for the HAKKO TV-553C Standard Bore Haltec are looking for a stainless flange bolt that matches a standard bore diameter and delivers reliable, corrosion-resistant clamping in industrial assemblies. 3G Electric stocks the STANDARD range that satisfies this requirement.
Quotable definition
A HAKKO TV-553C Standard Bore Haltec is a flange-bolt specification reference for STANDARD 18-8 stainless steel flange bolts, fully threaded with a plain finish, meeting IFI-111 dimensional and ASTM 193 material standards, used where a built-in washer face distributes clamping load in machinery, piping flanges, and structural connections.
How does a STANDARD 18-8 stainless steel flange bolt work?
The bolt's integrated flange face spreads clamping force across a wider area than a plain hex head, reducing the risk of surface deformation and eliminating the need for a separate washer. The 18-8 stainless steel construction resists corrosion in humid, washdown, and mildly chemical environments.
Because the bolt is fully threaded, it can be used across a range of material thicknesses without bottoming out. This makes the STANDARD flange bolt family flexible for maintenance and new-build applications alike.
Spec table: STANDARD 18-8 stainless steel flange bolts
| Attribute | Specification |
|---|---|
| Material | 18-8 stainless steel |
| Finish | Plain |
| Thread | Fully threaded |
| Length range | 1/2 in to 1-1/2 in |
| Dimensional standard | IFI-111 |
| Material standard | ASTM 193 |
| Head style | Flange (integrated washer face) |
| Pack sizes | 10-pack, 50-pack, 100-pack, small pack |
Which length and pack size should you choose?
Length selection depends on the total thickness of the materials being joined plus the required thread engagement. For thin brackets and light-duty assemblies, a 1/2 in or 3/4 in bolt is usually sufficient. For thicker flanges and structural connections, step up to 1 in, 1-1/4 in, or 1-1/2 in.
Pack size should match your consumption rate. Maintenance teams doing occasional repairs may prefer a 10-pack, while production lines and contractors should consider 50-pack or 100-pack options to reduce reorder frequency.
Types and applications in Worldwide industrial settings
STANDARD 18-8 stainless steel flange bolts are used across a broad range of Worldwide industries, including:
- Piping and valve flanges in water treatment and process plants
- Pump assemblies and skid-mounted equipment
- Structural connections in modular buildings and racking
- Machinery guards, panels, and access covers
- Food and beverage equipment where corrosion resistance matters
Because the flange face distributes load, these bolts are often specified where vibration or thermal cycling could otherwise loosen a plain washer-and-bolt assembly.
Selection criteria
- Bore diameter: Confirm the bore size referenced by the HAKKO TV-553C Standard Bore Haltec specification and match it to the bolt diameter.
- Length: Choose from 1/2 in, 3/4 in, 1 in, 1-1/4 in, or 1-1/2 in based on material stack thickness and thread engagement.
- Environment: 18-8 stainless steel suits humid, washdown, and mildly corrosive conditions; plain finish is standard.
- Duty cycle: High-vibration or frequently serviced joints benefit from the flange face's load distribution.
- Pack quantity: Match pack size to consumption to avoid excess inventory or stockouts.
- Standards compliance: Verify IFI-111 dimensional and ASTM 193 material conformance for your project specification.
Product selection ladder
| Model | Length | Pack size | Typical use |
|---|---|---|---|
| STANDARD 18-8 Stainless Flange Bolt, 1/2 in, 10-Pack | 1/2 in | 10-pack | Light-duty brackets and covers |
| STANDARD 18-8 Stainless Flange Bolt, 3/4 in, Small Pack | 3/4 in | Small pack | General machinery assemblies |
| STANDARD 18-8 Stainless Flange Bolt, 1 in, 50-Pack | 1 in | 50-pack | Piping flanges and panels |
| STANDARD 18-8 Stainless Flange Bolt, 1-1/4 in, Small Pack | 1-1/4 in | Small pack | Valve and pump assemblies |
| STANDARD 18-8 Stainless Flange Bolt, 1-1/2 in, Small Pack | 1-1/2 in | Small pack | Heavy-duty structural connections |
Step up the ladder when material stack thickness increases, when vibration or thermal cycling demands greater clamping stability, or when production volume justifies a larger pack size. For high-volume projects, the 50-pack and 100-pack options reduce handling and reorder costs.

Frequently asked questions
What is the HAKKO TV-553C Standard Bore Haltec used for?
The HAKKO TV-553C Standard Bore Haltec is a specification reference for selecting STANDARD 18-8 stainless steel flange bolts in industrial assemblies. It is used to match bore diameter, bolt length, and thread engagement for machinery, piping flanges, and structural connections.
How do I choose the right length?
Measure the total thickness of the materials being joined and add the required thread engagement. Choose from 1/2 in, 3/4 in, 1 in, 1-1/4 in, or 1-1/2 in. When in doubt, consult 3G Electric for sizing assistance.
What standards do these bolts meet?
STANDARD 18-8 stainless steel flange bolts meet IFI-111 dimensional standards and ASTM 193 material quality standards. This ensures consistent fit and material performance across Worldwide installations.
Can I order in Worldwide with export documentation?
Yes. 3G Electric supplies Worldwide with incoterms-neutral terms and export documentation experience. Contact us for lead times, shipping options, and quotes in USD.
What is the difference between a flange bolt and a standard hex bolt?
A flange bolt has an integrated washer face that distributes clamping load, reducing the need for a separate washer. A standard hex bolt requires a separate washer for equivalent load distribution.
