72 ANSS 8-12 (6.4 Ø x 23L) Anlock Countersunk ALL Steel Mega Lock Structural Rivet Grips 10.5-18.4mm

Product Overview & Applications

This 72 ANSS 8-12 (6.4 Ø x 23L) Anlock Countersunk ALL Steel Mega Lock Structural Rivet Grips 10.5-18.4mm is a precision-manufactured anlock mega lock structural rivet.

Technical Fastener Characteristics

• Head Style: Countersunk Head
• Product Type: Anlock Mega Lock Structural Rivet

Dimensions & Grip Range

• Body Diameter: 6.4mm (1/4")
• Grip Range: 10.5mm to 18.4mm

Material & Coating

Zinc silver plated is electroplated carbon steel — bright silver finish, typically 5-25 microns of zinc. Internal-use only — corrodes quickly when exposed to moisture, salt or weathering.

Indoor Use Only: Zinc plated finishes are designed for protected internal environments. Outdoor exposure, salt spray or treated-timber contact will corrode the coating within months. For outdoor use, specify galvanised or stainless instead.

  How Rivets Work

  Using a structural rivet tool, the rivet is ‘set’ by drawing the stem through the shell, which causes the body to expand/compress to distort and clamp the material securely. After the desired clamping force is achieved, the stem breaks off at a predetermined position and is discarded. A small portion of the stem remains trapped in the bottom of the shell to ensure the clamping force is retained in the joint. Blind rivets are designed to clamp together specific thicknesses of material. If the grip range is less than it should be (the rivet is too long), excessive material will be left on the blind side and more pulls will be required to break-off the mandrel. If the grip range is too large (rivet is too short), insufficient material may be left on the blind side to secure the joint

  Material Pairing

  As a general rule, the shell material of the rivet should be the same as the material under the head, ie, if aluminium is fastened to steel, use steel rivets. Part of the stem remains in the shell after setting. In the case of steel stems, this part may rust, an undesirable attribute in many circumstances. In these cases, choose a rivet with a stainless or aluminium stem

  Frequently Asked Questions

  Is this rivet suitable for outdoor or marine use?

  No — zinc plated finishes are internal-use only. Outdoor exposure, salt spray or treated-timber contact will corrode the coating within months. For outdoor use, choose galvanised or stainless instead.

  What is the tensile strength of this rivet?

  Yield 240 MPa, ultimate tensile 400 MPa. Mild-steel grade for general fastening below working limits.

  What thickness of material can this rivet fasten?

  This rivet's grip range is 10.5mm to 18.4mm — the total combined thickness of the materials you're joining must fall within this range. If the layers add up to less than the minimum, the rivet won't form a proper back-head; if more than the maximum, the mandrel won't pull through to set the joint.
