Chem-Set 3/16 In. x 1-1/2 In. T31 Sink Anchor Bolt Kit

Description

T31 sink anchor bolt gives countertop fabricators a stainless steel T-bolt, nut, and washer set for routed undermount sink anchoring where a clean top surface matters. This 3/16 inch by 1-1/2 inch hardware is used with T-slot style sink anchor layouts so installers can clamp clips and brackets from the underside without drilling through finished stone.

Key Features and Benefits

• Stainless steel hardware stands up well in sink areas that see moisture and repeated service.
• T-bolt profile fits routed T31-style anchor slots used in stone and solid surface fabrication.
• Nut and washer are included, which keeps installation crews from piecing together mixed hardware.
• Short 1-1/2 inch length works well when you need holding power without excess thread below the deck.
• Simple mechanical hardware makes clip replacement and sink service easier later.
• Useful for both shop production and field replacement of worn or missing anchor bolts.
