2.0 USES

The Hilti Low-velocity Power-Actuated Driven Threaded

Studs are used as alternatives to the welds and bolts used

to attach materials to structural steel, which are described

in IBC Sections 2204.1 and 2204.2, respectively. The

fasteners may be used for structures regulated under the

IRC, when an engineered design is submitted in

accordance with IRC Section R301.1.3.

3.0 DESCRIPTION

3.1 General:

Hilti low-velocity power-actuated threaded studs are

fasteners with male threads for attachment of building

materials on one end and a pointed- or blunt-tip shank on

the other end for embedment into the supporting steel. The

threaded studs are available with the thread designations,

shank diameters, lengths and materials shown in Table 1.

3.1.1 X-EW6H and X-EW10H Threaded Studs: These

pointed-tip studs are formed from carbon steel, hardened

in accordance with the manufacturer’s specifications, and

zinc-plated in accordance with ASTM B633 SC 1, Type III.

These studs are supplied with a plastic washer. See Figure

1 for a depiction of the fasteners.

3.1.2 X-ST-GR M8 Threaded Studs:

These pointed-tip

studs consist of a threaded sleeve and a drive pin. The

threaded sleeve is manufactured from SAE 316 stainless

steel. These studs are supplied with plastic washers.

The drive pin is manufactured from stainless steel

conforming to specifications in the manufacturer’s quality

documentation. See Figure 2 for a depiction of the

fastener.

3.1.3 X-BT Blunt-tip Threaded Studs:

3.1.3.1 X-BT M8, X-BT W10 and X-BT M10: These blunt-

tip studs consist of a threaded sleeve and a drive pin, and

may have a stainless steel/bonded elastomer sealing

washer, designated SN12-R. The threaded sleeve and

washer are manufactured from SAE 316 stainless steel.

The drive pin is manufactured from a proprietary CrNiMo

alloy complying with the requirements of SAE 316. See

Figure 3 for a depiction of the fasteners.

3.1.3.2 X-BT M6 and X-BT W6:

These blunt-tip studs are

formed as a single piece from a proprietary CrNiMo alloy

complying with the requirements of SAE 316 stainless

steel, and have a stainless steel/bonded elastomer sealing

washer designated SN12-R. See Figure 4 for a depiction of

the fasteners.

3.1.4 X-BT-MF: These blunt-tip studs consist of a

threaded sleeve and a drive pin, and have a combination

stainless steel/bonded elastomer sealing washer

designated SN4. They are also supplied with a plastic nut

or a stainless steel nut. The drive pin is manufactured from

a proprietary stainless steel conforming to specifications in

the manufacturer’s quality documentation. The threaded

sleeve is manufactured from glass-fiber-reinforced

polyamide material. See Figure 5 for a depiction of the

fasteners.

3.1.5 X-BT-MR and X-BT-GR: These blunt-tip studs are

formed as a single piece from a proprietary CrNiMo alloy

complying with the requirements of SAE 316 stainless

steel, and have a stainless steel/bonded elastomer sealing

washer. The blunt tip is slightly tapered. See Figures 6 and

7 for depictions of the fasteners.

3.2 Steel Substrates:

Structural steel must comply with the minimum

requirements of ASTM A36, ASTM A572 Grade 50 or

ASTM A992, and must have the minimum thicknesses,
