#8 x 2-1/2 flat head assembly screw describes a Wurth screw sized for assembly work where a flat seating head and consistent drive matter on the job. The sharp point coarse thread lubricated design lets the screw start quickly and pull down efficiently in typical woodworking and assembly tasks. The flat head style sits flush in a countersunk hole so hinge plates, brackets, or joining parts can bear tightly against the surface. The case hardened construction provides a tough outer layer that supports driving with power tools in production settings. The #2 square drive interface works with common square drive bits, giving positive engagement to resist cam-out during steady driving. The thread extending two-thirds from the bottom of this length supports strong hold while leaving some unthreaded shank for pulling parts together.
The sharp point coarse thread lubricated design on this Wurth #8 x 2-1/2 inch flat head assembly screw promotes quick starting and smooth driving in typical assembly materials. The thread running two-thirds from the bottom allows the lower section to cut in firmly while the unthreaded portion helps pull parts together as the head seats. The flat head geometry matches countersunk holes used in assembly layouts, so hardware or workpieces can rest closely over the head area once driven. The #2 square drive bit requirement means drivers engage the recess with four bearing faces, supporting controlled torque transfer. The case hardened construction further supports this installation style by reinforcing the head and drive recess during repeated use with powered drivers.
This Wurth #8 x 2-1/2 inch flat head assembly screw is identified as case hardened with a sharp point coarse thread and lubrication, positioning it for assembly work where many fasteners are driven in similar materials. The thread extending two-thirds from the bottom is specifically called out for lengths other than 3/4 inch and 1 inch, so this 2-1/2 inch length uses that configuration to draw joined parts together while the tip anchors firmly. The flat head style fits countersunk patterns typically used in assembly joints, letting components, brackets, or plates sit close over the fastener location. The #2 square drive requirement matches widely used square drive bits, which matters in shops that standardize on a single drive type across assembly stations. The Wurth branding and part 3670000173961 2500 description connect this screw to Wurth Baer Supply inventory, which supports ongoing sourcing for repetitive shop processes.
The case hardened description on this flat head assembly screw means the outer surface is hardened, which helps the threads and square drive recess resist wear during repeated powered driving. The sharp point coarse thread pattern and lubricated finish described in the product name work together to reduce driving friction and support steady advance into material, which is useful when maintaining uniform clamp pressure across multiple fasteners. The two-thirds-from-bottom threading used on this 2-1/2 inch length allows the unthreaded portion near the head to act as a clamp zone, helping parts close tightly as the screw is driven. The specific identification as a #8 size flat head assembly screw defines the shank and head style that match typical countersink sizes used in assembly layouts. The requirement for #2 square drive bits gives installers a clear driver interface so they can match their bits to the screw head and maintain consistent engagement while driving.
This Wurth #8 x 2-1/2 inch flat head assembly screw uses a #2 square drive, which provides positive bit engagement during driving.
The 2-1/2 inch length is described as threaded two-thirds from the bottom, which leaves an upper shank section to help pull parts tightly together.
This flat head assembly screw is case hardened, giving the outer surface added hardness to support the threads and drive recess under driving loads.
The flat head design allows the screw to sit flush in a countersunk hole so joined parts or hardware can bear directly against the surface.
The sharp point coarse thread configuration lets the screw start quickly and advance efficiently into material for assembly work.
The description 3670000173961 2500 and 2500/Box indicate this product is supplied in a box containing 2,500 screws for high-volume use.
This Wurth #8 x 2-1/2 flat head assembly screw square drive sharp point coarse thread lubricated design, identified as part 3670000173961 2500, combines case hardened construction, two-thirds bottom threading, and #2 square drive engagement for controlled assembly work. For projects needing a flat head that fits countersunk layouts and a coarse thread that advances efficiently, this screw offers a defined size and performance profile that supports repetitive fastening across woodworking and assembly jobs.
