Typical Lockbolt Performance
Tests and expectations

Test results (minimum values) in bold

Expectations in italics

Tests were carried out using full (regular) collars and products with standard finishes (zinc plated for steel pins, alochrom for aluminium and self colour for stainless steel). Other finishes and other collars can produce different results.

The above figures cannot be used as minimum specifications as conditions of use are totally outside our control and can produce different results.

Our test program is ongoing.+
