Overview
G CLEVIS METRIC Product Overview
G 4×8 est une chape métrique de série G avec filetage M4, alésage d’axe (d4) de 1 mm et longueur d’axe (l8) de 1 mm. Largeur du corps (w3) = 8 mm, longueur hors tout du corps (l2) = 21 mm. Poids approximatif : 5 g.
Fabriqué en acier Q235 avec zinguage argent. La chape de série G est un embout à fourche femelle qui reçoit un axe de chape dans son alésage, permettant une connexion articulée à un support ou un œil de tringlerie complémentaire. L’extrémité filetée se raccorde à un actionneur métrique, à une tige de vérin ou à un adaptateur de tube. Utilisé dans les tringleries de vérins pneumatiques, les commandes d’automatisation, les actionneurs de vannes et les ensembles de chapes métriques polyvalents.
Filetage à gauche disponible — ajoutez le suffixe ‘LH’ (ex. G×4x8LH). Versions en acier inoxydable et aluminium disponibles sur demande. Axe de chape, rondelle et goupille fendue disponibles séparément. Option chape à goupille élastique disponible.

FAQ
G CLEVIS METRIC Frequently Asked Questions
What is the G 4x8 clevis used for?
The G 4x8 is a metric G-series clevis with a M4 threaded stud end and a 4 mm pin bore, built as a female fork fitting for pneumatic cylinder linkages, automation controls, valve actuators, and general-purpose metric clevis assemblies. The threaded end connects to a mating actuator, cylinder rod, or tube adapter, while the bore accepts a clevis pin so the fitting can pivot against a bracket or linkage eye.
What thread does the G 4x8 use, and is it a coarse or fine pitch?
The G 4x8 is threaded M4, a standard metric (coarse) pitch — SYZ does not list a fine-pitch "FG" variant at this bore/length combination, so this is the only pitch offered for this size.
What pin bore and pin length does the G 4x8 clevis have?
Pin bore (d1) is 4 mm and pin length (l1) is 8 mm, sized to take a 4 mm clevis pin through the fork bore for the articulated connection.
What are the overall body dimensions and weight of the G 4x8?
Overall body length (l2) is 21 mm, body width (w3) is 8 mm, hub diameter (d3) is 8 mm, and fork throat depth (l4) is 6.0 mm. Approximate weight is 5 g (0.01 kg) — check these against your linkage clearance and handling requirements before ordering.
What material is the G 4x8 made from, and are other materials available?
Standard construction is Q235 steel with a silver zinc-plated finish. Stainless steel and aluminum versions are available on request — confirm material and finish when requesting a quote.
Is a left-hand thread version of the G 4x8 available, and what hardware completes the assembly?
Yes. Standard thread hand is right-hand; add "LH" to the part number (e.g., G×4x8LH) to order the left-hand thread version for turnbuckle-style or opposing-thread linkage builds. Clevis pin, washer, and cotter pin are available separately, and a spring-pin clevis option is also offered.
