Structural Blind Fastener

Avbolt®

The Avbolt structural fastener is a high strength, tamper

resistant, blind steel fastener designed for use in heavy-

duty structural applications such as automotive, con-

struction, container, railway and mining.

It expands the range of POP Avdel structural bolts by

offering high tensile and shear strength (normally only

possible with non blind lockbolts) with the versatility of

single sided installation; ideal for areas with restricted

access.

The Avbolt fastener is simple to use, with fast, positive

single sided installation, requiring minimal operator

skill. The locking feature creates a vibration resistant

joint and prevents loosening stems. Ease of inspection

for correct installation and excellent tamper resistance

are further advantages.

Key features and benefi ts

• Use on blind sided application

• High tensile and shear strength for heavy-duty

applications

• Wide grip capability suits a variety of material

thicknesses

• Locking feature creates a vibration resistant joint and

prevents loose stems

• Ideal for areas with restricted access

• Fast installation

• High security tamper resistance

• Simple tooling requires minimal operator skill

Typical placing sequence (3 piece design) Removal

Avbolt fasteners are de-

signed to create a perma-

nent fi xing. This provides

security benefi ts and

enables the fastener to be

TIR approved. If removal

is needed, the fasteners

can be removed using an

angle grinder and punch.

For details see removal

procedure on our website. 1. Insert the Avbolt fastener in the hole and insert the stem into the nose piece of the placing tool.

2. First operation pulls the pin-tail to form the bulb. The sleeve is band annealed (soft zone) to ensure the bulb forms in exactly the right place. Once the bulb has formed, the clamp up force is applied to the joint pulling the work pieces together. The collar material is then swaged into the pin lock grooves, trapping the clamp up load and forming a tamper proof lock.

3. At a pre-determined load, the pin breaker groove fractures; the pintail is detached and the joint is complete.

Placing performance

Structural Blind Fastener for Heavy Duty Applications

When an Avbolt fastener is placed in maximum recom-

mended grip, the stem breaks flush to the collar. When

placed in minimum grip, the stem breaks above collar

and the bulb is spread more providing a larger foot

print.

The flange on the collar (21001 series) prevents the

anvil from contacting and damaging the work surface.
