Expansion Sleeve PGB M5 x 20 mm, brass, pack of 100

Brass expansion sleeve PGB M5 x 20 mm, supplied in a pack of 100, is an anchor sleeve designed to receive M5 bolts or screws in solid base materials. The sleeve expands when a threaded fastener is tightened, creating radial pressure that secures the fastener in masonry and other dense substrates. Supplied as a bulk retail pack, these brass sleeves are intended for use where a metal anchor is preferred for corrosion resistance and mechanical stability.

Advantages

Brass construction offers increased corrosion resistance compared with some ferrous anchors, making the sleeve suitable for indoor environments and some non-aggressive external conditions. The 20 mm length provides engagement depth for short-to-medium anchoring tasks where M5 threaded fasteners are appropriate. Pack of 100 ensures availability for multiple fixings and reduces the need for frequent reordering on small to medium projects.

Suitable for

• Anchoring M5 bolts or screws in solid masonry, brick and concrete
• Temporary and permanent fastenings in construction and installations
• Mechanical assemblies where metal anchors are required
• Electrical and plumbing fixture mounting to solid substrates

Key specifications

• Material: brass
• Intended fastener size: M5
• Length: 20 mm
• Quantity per pack: 100 pieces
• Application: expansion-type anchor for solid base materials

How to use

Drill a hole in the base material with the correct drill bit size recommended for an M5 expansion sleeve and clean out dust and debris. Insert the brass sleeve into the hole so that it sits flush with or slightly below the surface. Insert the M5 bolt or screw through the fixture and into the sleeve, then tighten to the required torque to cause the sleeve to expand and lock against the hole walls. Verify the fastener is secure and aligned before completing the installation.

Usage recommendations

Use the sleeve only in suitable solid substrates; avoid hollow or crumbling materials without additional support. Select the correct drill bit and tightening torque for M5 fasteners to achieve reliable load distribution. For outdoor or highly corrosive environments, consider the local conditions and consult material compatibility guidelines before use.
