Hollow Section (HSS) ConnectionsThe Hollo-Bolt® and Lindibolt™ eliminate the need for conventional through-bolting or welding of hollow structural section (HSS) or any steel structure where access is only available from one side.

Both the Lindibolt and Hollo-Bolt enable fast, safe construction and can be swiftly installed by simply inserting the product into pre-drilled holes, then tightening to the recommended tightening torque using hand tools.

In the late 1940s, Lindapter revolutionized ‘blind connections’ with the development of the original Lindibolt, for situations where access to both sides of the steel was restricted. Following the introduction and wide acceptance of HSS, the Hollo-Bolt was invented to suit virtually any type of hollow section, including square, rectangular, circular and oval profiles. As with all Lindapter products, the R&D department has continued to develop the range with the rapid expansion in diameters, lengths, finishes and head types.

Following comprehensive testing, The Steel Construction Institute (SCI) and British Constructional Steelwork Association (BCSA) recognize the Hollo-Bolt as a primary structural connection, in the design guide ‘Joints in Steel Construction – Simple Connections’. The American Institute of Steel Construction (AISC) also recognizes the Hollo-Bolt as a HSS connection in the Steel Construction Manual.

Typical Hollo-Bolt applications include:• Primary Connections• Secondary Connections• Bridges• Cladding• Balconies• Towers and masts• Staircases and handrails • Glazing and roofs

The Original Expansion Bolt for Structural Steel is ICC-ES approved for compliance with the International Building Code®

Type HB - Hollo-Bolt®

Steel, bright zinc plated plus JS 500 Steel, sheraplexSteel, hot dip galvanized Stainless Steel Grade 316

Suitable for hollow sections, tubes and where access is available from one side only. The Hollo-Bolt is continuously developed to meet the requirements of Structural Engineers, with recent performance improvements including the patented High Clamping Force (HCF) version (see page 40). The Hollo-Bolt is protected by multiple international patents and registered designs.

Hexagonal Countersunk (Bolt Head)

Flush Fit

Countersunk (Bolt Head) Visible protrusion: MinimalThis discreet midway option has a smaller protrusion for the perfect balance of appearance and convenience, and features a Grade 10.9 (A490 equivalent) countersunk bolt with a special collar designed to accommodate the entire bolt head. Drilling countersunk holes in the steel section is not required.

Flush FitVisible protrusion: ZeroThe innovative Flush Fit Hollo-Bolt is entirely concealed within a drilled countersunk hole once installed, leaving no protrusion above the surface of the steel section - the perfect solution for architects!

Lindapter Hollo-Bolt Head Variations

HexagonalVisible protrusion: RegularThe Hollo-Bolt collar and hexagonal head of the Grade 8.8 bolt (Grd. 5 / A325 equivalent) are evident above the surface of the steel section. This head variant is the usual choice for the majority of HSS connections, or where architects favor an ‘industrial’ look.

Sizes M16 ( 5/8” ) and M20 ( 3/4” ), known as the Hollo-Bolt HCF, feature a patented High Clamping Force mechanism to produce three times more clamping force than the same sized product without the mechanism. The significance of clamping force and the superior performance of Lindapter’s unique Hollo-Bolt HCF is illustrated on page 40.

A typical connection is made by inserting the Hollo-Bolt into the pre-drilled holes of the fixture and hollow section. As the bolt head is tightened, the cone is pulled up the bolt thread, causing the legs of the sleeve to expand until the cone locks the sleeve against the inner wall of the hollow section.

At full tightening torque, a clamping action is set up between the fixture and steel section to form a secure connection.

Working closely with Structural Engineers & Steel Fabricators, Lindapter identified the need for the larger M16 (5/8”) & M20 (3/4”) Hollo-Bolts to have an increased clamping force suitable for higher strength structural connections. Research & Development led to the invention of the patented 5-part design, optimized for superior performance.

The High Clamping Force (HCF) mechanism consists of a special washer that ‘compresses’ to significantly increase clamping force between the fixture and hollow section, when compared to a 3-part product of the same size, thereby reducing displacement.

Clamping ForceAs with any structural bolt, immediately after installation the bolt relaxes until a typical clamping force is reached. The typical clamping force of the Hollo-Bolt HCF is over three times higher than the same sized product without the HCF mechanism. This results in a more secure connection and a greater force that has to be overcome before displacement begins.

The Hollo-Bolt can be used on a wide variety of steel hollow sections; safe working loads shown are based on use in A36 Structural Tube. The safe working loads, in both tension and shear, are applicable to the Hollo-Bolt only. Failure of the section, particularly on those with thin walls and a wide chord face, could occur at a lower figure and strength of the section should be checked by a qualified Structural Engineer.

2.0 USES

Hollo-Bolt® Fasteners are designed for connecting structural steel to hollow structural section (HSS) steel members and other structural steel elements where access is difficult or restricted to one side only. Hollo-Bolt® fasteners are intended for use with rectangular or square HSS members and are recognized for resisting static tension and shear loads in bearing-type connections. The fasteners are alternatives to bolts described in Section J3 of AISC 360, which is referenced in Section 2205.1 of the IBC, for bearing-type connections.

The Hollo-Bolt® Fasteners may be used to resist wind loads, and seismic loads in Seismic Design Categories A, B and C.

3.0 DESCRIPTION

3.1 General:

Hollo-Bolt® 3 Part Fasteners are assembled from three components, consisting of the core bolt, the body (sleeve) including the shoulder (collar), and the cone. The steel core bolt features a threaded shank and hexagonal head. The body is a steel segmented hollow cylinder, with four

slits 90 degrees from each other. The collar is a circular element having two flat surfaces (to accommodate an open-ended wrench) with a circular hole integral with the sleeve. The cone is a steel circular internally threaded nut with grooves on the outer surface. Nominal Hollo-Bolt® sizes include 5/16 inch (M8), 3/8 inch (M10), 1/2 inch (M12), 5/8 inch (M16), and 3/4 inch (M20), with each size of bolt available in three lengths.

The Hollo-Bolt® 5 Part Fasteners are similar, except that they include a nitrile rubber washer and separate collar. Figure 1 provides a picture of the Hollo-Bolt® 3 Part and Hollo-Bolt® 5 Part. Table 1 provides part codes, design strengths, and installation information.

3.2 Materials:

3.2.1 Set Screw: The core bolt is manufactured from steel complying with EN ISO 898-1, Class 8.8, having a specified Fu of 116,030 psi (800 MPa).

3.2.2 Body (sleeve) with Integral Collar, Body (sleeve without collar), Collar and Cone: The parts are manufactured from free cutting carbon steel Grade 11SMn30 or 11SMnPb30, conforming to BS EN 10087, having a minimum tensile strength of 62,400 psi (430N/mm2) (sizes up to LHB16) or 56,500 psi (390N/mm2) (size LHB20); or cold drawn steel AISI C10B21, having a minimum tensile strength of 68,000 psi (470N/mm2).

3.2.3 Rubber Washer: The shore hardness is measured on the A scale 80-90.

3.2.4 Finish Coating: All components, except the rubber washer, are hot dipped galvanized/high temperature galvanized to BS EN ISO 1461, as described in the quality documentation.

4.0 DESIGN AND INSTALLATION

4.1 Design:

The fasteners are alternatives to bolts described in Section J3 of AISC 360, which is referenced in Section 2205.1 of the IBC, for bearing-type connections. The design of the Hollo-Bolt® Fasteners must comply with this report, Section J3 of AISC 360 and the strength design information for the Hollo-Bolt® provided in Table 1 of this report. The load-carrying capacity of the assembly depends on the fasteners, the type of elements connected, such as a HSS and its their cross
