SpecialInsert F1 Female B23 – 23mm Round, 1/4″-20 Thread, Stainless Steel Fastener – CCH-SSF1B23-1/4-20

Description

The Specialinsert F1 is a female bonding fastener on a 23mm round stainless steel base, built to pair with an M1 male threaded post for a complete no-drill mounting system. The female receiver threads onto the post after both halves are bonded in place, giving assemblers a bolted connection without ever touching a drill to the substrate.

How this female bonding fastener pairs with the M1 system

Bonding fasteners work in matched pairs: a male stud bonds to one surface, and a female receiver like this one bonds to the mating surface or component, and the two thread together to complete the joint. Because both halves attach with adhesive rather than mechanical fastening, they suit through-hole and blind-hole applications equally well. There is no requirement to drill, tap, or access the back side of either surface before bonding. Once cured, the female base transfers load into the substrate across its full 23mm bonded footprint rather than concentrating stress at a single drilled point.

Why shops choose a female bonding fastener over drilling

Drilling and tapping a hole into finished stone, composite panel, or coated metal risks cracking the substrate, chipping a finish, or leaving a visible repair mark that is hard to hide. A bonded fastener sidesteps that risk completely since the mounting point goes on with adhesive instead of a drill bit. That makes this style of fastener a common choice for retrofit work on finished surfaces, for materials that do not tolerate drilling well, such as natural stone, composite panels, and thin-gauge sheet, and for any assembly where a drilled hole would compromise a weatherproof or cosmetic surface.

Specifications

• Type: Female threaded bonding fastener (pairs with M1 male post)
• Base: Round, 23mm diameter
• Thread size: 1/4-20
• Material: Stainless steel
• Installation: Adhesive-bonded, no drilling or welding required
• Application: Through-hole or blind-hole

Bonding fasteners also cut assembly time compared to welding. There is no weld spatter to grind off, no heat distortion to correct, and no refinishing pass needed after the joint is made, so a bonded stud-and-receiver pair like this one can go straight from placement to cured joint without a secondary finishing step.
